I hope Theymos can find time to comment here.
Possibly, if you're lucky.
If i'm "lucky"? Ok, lets see if I can tempt him here.
"Viewing all members is temporarily disabled"
https://bitcointalk.org/index.php?action=mlistSo, It is painstaking to research this topic of "who" is spamming.
The (main) period of time in question by OP is when accounts 600,000 - 700,000 were created, that period was Oct/Nov/Dec 2015, approx.
If you view the "forum history", (
https://bitcointalk.org/index.php?action=stats) at the bottom of the page you will see in October 2015 68832 people joined bitcointalk. (up 9 fold from 7727 in sept, and more than joined in the previous 6 months)
Followed by 44058 in Nov 2015, and 39950 in Dec 2015 (and for several months after, maybe these accounts are too new for OP to have "noticed" these yet)
I know these figures are not conclusive to account farming. But coupled with my previous observations, maybe more so.
Also, I have found other massive "attacks".
In Oct 2015 (rough figures as guide, impossible for me to study properly) created accounts consist mainly of (or i was just very lucky to "hit" target)
Accounts between 572000 and 575000 are "btcRDkill_"
Accounts between575000 and 600200 are "MrFudged1_"
Accounts between 600200 and 625000 are "KNC_areThief"
(all followed by different numbers)
Over 50 thousand there. Again, i know these aren't "all" countable, but most seem to be. Have a go yourself. (i have no tools here) Pick a number between u=572000 and u=625000. Which one above did you hit?
Also endless (unused) MMMglobal accounts. Are they responsible for all of this? Pick a number between OP target u=600000 to u=700000. (guess, 1 in 5 chance to hit)
Also the strange letters at the end of names I previously mentioned, and Connected. Take your pick of target u=, very good chance to hit.
These accounts are All(?) inactive?
Are these accounts already banned? Or just waiting. I cannot know.
I previously linked (some of) OP listed active accounts. There are many more "patterns" which are easily findable in these active farmed accounts.
They are all bought up to status by posting once a fortnight. the minimum post to max potential?
(you need to look at the first posts on the account. it may be sold now)
Christmas day wont stop the system. (i know, why should it)
But for fun(!) look at "stadus",

This pattern runs right through OP target period
Look at "efemen" (from OP list)
https://bitcointalksearch.org/user/efemen-667865And compare with (all registered within 8 minutes)
"Falmant"
https://bitcointalksearch.org/user/falmant-667868"Gatotare"
https://bitcointalksearch.org/user/gatotare-667872"Hamaber"
https://bitcointalksearch.org/user/hamaber-667873 They posted on (from first posts remember)
Dec 27, Jan 5/16/27, Feb 9/22
Dec 27, Jan 6/17/29, Feb 10/23

It is MASSIVE.
It's not an effortless job to rank up a bunch of BS accounts, especially if they're enrolled in signature campaigns that have rules, and it's not a super high-paying one either. In fact, it takes some sort of hardcore, dedicated, insane scoundrelly type to come up with this shit to make money.
Correct. However, keep in mind that the problem is also caused by the signature campaigns themselves. They usually are not putting up enough pressure on their participants regarding quality, or just don't care at all. As long as there's no regulation, and not enough pressure from the stuff the situation will keep degrading.
Clearly these farmed spammers will just keep coming en masse. You will never keep up with them.
If I can stumble on this, you must already know.
Is this Anti spam thing all a pretence?
Theymos must know all this and could act.
It would "kill" spam overnight.
Why hasn't he acted?
(OP, you have listed
https://bitcointalksearch.org/user/dumana-658316 twice. and maybe another. could you order them in sequence and maybe include user names. more human friendly than the present list!)
