That forum name was icoforums.net but that was a very small project as compare to crytotalk funded by yobit.net.
Even if they do not start a new competition, the posting on that forum will never stop as they are still paying 1000 satoshi to each and every single post and comment.
Unless they stop. That's the point. ICOForums had traffic while people were getting paid for that. When that was over, the forum died.
Spammers will only stay in CryptoTalk until they end the 1000 sat/post campaign (if they do).
