The best thing to clean this forum from spammers is to remove altcoin section where newbies are spamming their shitty coins just to get a piece of money. The forum should be all about bitcoin only, since it's bitcointalk.org.
It doesn't mean that the posts from the forum are only bitcoins discussion because it is entitled as bitcointalk. Still, altcoins are being traded into bitcoin. Why do we need to remove Altcoin section if it can help all the member here in the forum.
The removal of bounties and signature campaigns from ICOs will help clean this forum from spammers and shitty posts from newbies ranking their way up.
Well at least it will lessen the number of shitposters around here, but the time will come that forum will be deserted and the amount of shared discussion will decrease. Only members who have lovely bitcoin will be left here for knowledge.
