Not quite like that but, that sound usefull too in giving some more insight on the merited post.

I meant to run different kind of automated check on merited comments wrote from low rank members since as we can see, may have higher chances to have been faked.
So running few different kind of automated techniques, (even if they take several seconds per post) on few thousand messages is going to be easier than do the same on every single unmerited post.

So more or less targeting "newbie/"/low ranking members w/ 1 merit+.

We could add a script where it does the above, and then looks at top senders of merit to newbies for abuse. Although there may be legitimate senders within that list.

Another thought i had about plagiarism.

As far as i can see the main goal of faking content is just obtaining merits, wouldn't save a lot of time and resources to just check directly messages which receive merits, like every friday.
If from those you even remove messages from higher ranks, which are unlikely to risk the account, this reduces the total number to be checked to a very small fraction.
More manageable and the possibility to run deeper and lengthy methods to verify the content is authentic.

So like contrasting the # of merits against the quality of post, generating a list of users to be looked into? Excluding merits sent/received by HQ members?

Let me know if I got that right.

It's not a bad idea. Would still require some manual labor & not be completely automated. I'll throw it on the list if it's cool with you?

I'd just have to write a side-script to prevent users from just wrapping their messages in ["quote"] tags.
Quoted text isn't counted for payment for signature spammers, so they're unlikely to hide their plagiarism that way.

Never knew that. But I can’t see why some one would copy-paste. Good to know it’s checked. At first glance BTT looks complicated for me. But I now understand the complicated for a lot of reasons.

Copy/pasting is rampant on this forum. For bounty sig scammers it's the easiest way to get a high post count in a quick amount of time while looking like you're spending the time to write out a post.

Because most campaign managers have to manage many participants, plagiarism (copy/pasting) can get overlooked.

TBH, by building these scripts, campaign managers should have an easier time (in theory).

Update: added ideas sent from a user in PM: account quality detection

Update 2: adding idea for detecting trust abuse

Good idea, I think we should report the whole bounty board as plagiarism Smiley

Code:
foreach($forum_categories as $category_name => $category_values) {
if($category_name == 'Bounties (Altcoins)') {
foreach($category_values['posts'] as $post_id => $post_content) {
BitcoinTalkAPI::report($post_id);
}
}
}

Well that's done Wink (was gonna write it in python, but I've been coding with PHP all day so)

there are a lot of users who use actively bounty work & majority percent bounty post almost like same. Not only that script will detect similarity percentage so bounty post approximately 60/70% similar to each others. So how could it detected this script.

TBH, that's kind of the point. We'd have to determine a percentage of similarity that we agree is "report-worthy"; but I wouldn't be surprised if these scripts report a large amount of bounty users.

I'd just have to write a side-script to prevent users from just wrapping their messages in ["quote"] tags.

I guess, is that a standardized thing among all campaign managers though? I'm guessing eventually it would become rather obvious to them though. Definitely not a top priority script if required.

If it is using synonymous is becoming quite complicated, you need to be able to identify two different words are actually the same. Peraphs as you read the sentences you should substitute words with a code wich corresponds to a subset of synonymous then use these cleaned sentences to run the checks.
Maybe there are dictionaries ready for this sort of things. In any case comparing 1 message with all the previous message running perhaps multiple check can be quite expensive to perform.

There are dictionaries and other methods to deal with synonyms but they don't work well for crypto-themed texts without a serious ML effort. Worse yet, Bitcointalk text spinning bots don't really care much if the text makes sense so they'll replace "cryptocurrency" with "financial encoding" or some bullshit like that. Semantic comparison seemed quite useless to me so far in this context though I'm not an expert by any means - just learning as I go.

Few thoughts about the spinned texts:

If the spinned text is not using synonymous it may help before to run any check to prepare the data, for example reorder all the word of the sentence in alphabetical order.

If it is using synonymous is becoming quite complicated, you need to be able to identify two different words are actually the same. Peraphs as you read the sentences you should substitute words with a code wich corresponds to a subset of synonymous then use these cleaned sentences to run the checks.

The difficulty will be to find sources to match against (unsure if scraping Google will be permitted, we'll see).

Google has a search API. Not sure if there is a free tier though.

Considering their pricing change on maps, I'm going to assume not. I'll look into it though, thanks Smiley

@LoyceV: I'll make a note that if comparing messages for plagiarism, we should probably be ignoring ["quote"] tags within our scripts. I know it would probably make plagiarism detection more reliable, I'd just have to write a side-script to prevent users from just wrapping their messages in ["quote"] tags.

Tinker a little with the number of words and the threshold for detection of duplicates, and you're probably almost there for a large share of the copy-pasta spam.
I'm more worried about the very high number of positive results. Let me play around a bit with yesterday's data, from post 45850092 up to post 45893434. My scraper caught 43184 out of 43343 posts (it misses some burst posts). This is after the new Merit requirements, so there's less spam already.

I'll show the 50 most used posts (raw HTML excluding quotes; the number at the start of each line shows how often they appear). Those posts are exactly the same each time they were posted:

The first line is my own description. It's mainly caused by bounty spammers: they quote their own old post, then edit it to add their latest bounty report spam. My scraper catches the posts before they're edited.

This doesn't really catch plagiarism, but it catches spam. When you're looking for word phrases to detect plagiarism, you're likely to get even more hits than this.

The second entry came from Cidonar, who bumped this thread 162 times. That board shouldn't allow deleting posts within 24 hours, but it does.
The user isn't banned, as he deleted the evidence.

The third entry ("Proof of Authentication") came from many different users in this thread. I've just reported a few asking to check the thread.

The sixth entry ("microguy talks to himself") came from BitCoin ranger, who had 24 posts deleted by moderators.

Manually going through this list is a lot of work, while there aren't many posts to report. It's not very effective to do.

Tinker a little with the number of words and the threshold for detection of duplicates, and you're probably almost there for a large share of the copy-pasta spam.

I experimented with n-grams a little bit and couldn't find a good value. Low n yields too many false positives, high n doesn't detect spinners, etc. So I'm using a mixture of algorithms and base the decision on the pattern of the results of those algorithms - e.g. if the similarity of two texts using algorithm A is 70%, then union/intersect/otherwise manipulate the texts, run algorithm B, if it scores 90% then run algorithm C to eliminate false positives - made up numbers but you get the idea. Works ok-ish, but as I mentioned it doesn't scale well and I need to do more testing on larger samples.

The difficulty will be to find sources to match against (unsure if scraping Google will be permitted, we'll see).

Google has a search API. Not sure if there is a free tier though.

I don't know how it works but I think there is a bot on Steemit "@cheetah" that detect plagiarism, thus developing a similar bot wont be a problem (there are many senior developers in this forum).

It will be great if you succeed to write a script that detects members sendig Merits to each others.

I don't think it is going to be hard to code such script but you will need an access to the Merit database.

There's plenty of paid APIs to support plagiarism detection externally, so if I was lazy and rich I'd use those lol. Although, I'm uncertain of their reliability.

But realistically, external plagiarism detection isn't super difficult; although it may be more difficult than internal detection. I won't go too far into details (hashing, storage methods, etc), but essentially you're taking the copy of the text (or portions of it) & matching it against search engine results / meta descriptions.
I'm sure there's plenty of other methods as well.

The difficulty will be to find sources to match against (unsure if scraping Google will be permitted, we'll see).

Point is though: if 3 different developers develop it 3 different ways (using different sources) it will be far more difficult for bots/spammers to reverse engineer/abuse.

If you're working on plagiarism detection already, I'll probably work on multiple account detection first. Granted, multiple bots running from different developers with different sets of algorithms probably isn't a bad idea (will make it harder for bots to avoid)

I think we can certainly run multiple attacks on plagiarism as long as we coordinate to reduce overlap in which users we've reported etc, e.g. using the thread I mentioned and also https://bpip.org to check for bans.

With the little time I have available I'm still probably weeks away from a reasonably usable product and even then it would cover only a relatively small set of potential plagiarism. LoyceV mentioned that forum gets ~50k posts a day - many of which can be ignored or whitelisted but still that's a lot of garbage to sift through.


Maybe we can create some sort of central location for defining which users have been reported by bots.
If I have time, maybe I'll create something web-based, and just give out API keys to users who can prove they have an operating script.

Would just sort of be a web-based platform to set which users are reported by scripts/bots, and then it would track if those users actually have a ban through the use of BPIP (If Vod permits)

Dumping the info into a thread probably isn't ideal, but worst comes to worst we can rely on that until a more advanced system is produced.

If it helps you guys to know about declared alts, here are mine.

Thanks Jet Cash, if I do implement an alt detection system, I'd make the reporting of users more manual than automated.
I'm sure there's many users (such as yourself) who have alts for various reasons and aren't being nefarious and don't deserve a report.

If anyone has any further ideas for methods, keep em comin' Smiley

Detecting the text spinners will be a whole different level!
I guess a quick and dirty approach could be something like this:
1. take samples of all occurrences of 4 consecutive words
2. create their md5 (or whatever you prefer) hashes
3. store those hashes in a database
4. count number of hash collisions with other posts

So, a simple text like:
The quick brown fox jumps over the lazy dog

would result in 6 individual hashes:
The quick brown fox
quick brown fox jumps
brown fox jumps over
fox jumps over the
jumps over the lazy
over the lazy dog

Tinker a little with the number of words and the threshold for detection of duplicates, and you're probably almost there for a large share of the copy-pasta spam.

I don't think it is going to be hard to code such script but you will need an access to the Merit database.

We already have several tools for this purpose, you can see one here done by @DdmrDdmr

I don't know how it works but I think there is a bot on Steemit "@cheetah" that detect plagiarism, thus developing a similar bot wont be a problem (there are many senior developers in this forum).

If you're working on plagiarism detection already, I'll probably work on multiple account detection first. Granted, multiple bots running from different developers with different sets of algorithms probably isn't a bad idea (will make it harder for bots to avoid)

I think we can certainly run multiple attacks on plagiarism as long as we coordinate to reduce overlap in which users we've reported etc, e.g. using the thread I mentioned and also https://bpip.org to check for bans.

With the little time I have available I'm still probably weeks away from a reasonably usable product and even then it would cover only a relatively small set of potential plagiarism. LoyceV mentioned that forum gets ~50k posts a day - many of which can be ignored or whitelisted but still that's a lot of garbage to sift through.
