Report the posts. Most of them are dealt with within a few hours and it seems that when a moderator/admin has seen the reports they are able to rapidly delete them, at least faster than you can report. There's literally thousands of posts which should be deleted in that section a day. mprep is fighting a losing battle as well as the other globals/admins which step in to help at times.
It's really the combination of every aspect of the system:
-sig bounties
-hype
-the freedom to create any ico/coin for free
-last but not least the absurd amounts of money to be made from noobs.
It must be frustrating for the mods that this forum is becoming a vital part of the mechanism that makes the whole cryptoscene look like the wild west. It was fun for a while but now it's getting out of hand.
But there are ways of doing quality checks. There are numerous sites analysing icos on different aspects like transparency, funds allocation etc. You can set out minimum criteria for icos and coins. Now people look at the number of pages and 'the community' which is indeed mostly a pack of paid shills.
It doesn't matter on the project legitimacy it will be spammed regardless. If users can get free coins, via a airdrop for example they will spam that thread with both off topic replies and shitty posts like "Good luck". Although, this sort of spamming does happen in every single topic created in the annoucement, bounties and tokens sections there is a pattern in that promise of free coins via airdrop or some sort of other method results in more spam.
Honestly, the only way you would actually combat this is by limited users further and only allowing certain members to post in these sections. Then you are hurting those that are legitimately contributing to the thread. No one likes restrictions and you often see many higher ranked members suggesting newbies jail and other similar restrictions. Why? Because they wouldn't be limited by these restrictions so they only see it as a good solution and not the hassle it generates for those who actually want to contribute.
Again, this wouldn't even work. Take a look of my list here:
https://bitcointalksearch.org/topic/m.28395872That includes only members and up. Most of those linked have been spamming several threads in the altcoin section. This was only collected in 2/3 days. It isn't just lower ranked members which are the problem here.
Have you noticed the amount of threads and posts there? I've been here for 4 years and the last few months it's getting completely out of hand. I counted: in half an hour you get 4 (!) pages of new posts just in the ANN section. 4!!! Every 10 minutes there seems to be a new ICO or coin. This needs to stop, there needs to be some quality check. Any suggestions?
You can quality check the original posts as much as you want. Most of them would likely get through because it isn't the thread itself that is the problem. It's the people posting in them (paid to do so or not) which is the major problem here. The mods can't manually go through all the posts and quality check and whitelist all of the replies which get posted in these sections.
