It is another forum for crypto currencies that were launched by either the Yobit team or other entities that partnered with the Yobit exchange. And it was being marketed by the Yobit team here in bitcointalk forum so there is a big chance that cryptotalk.org is owned by Yobit.

I also visited the forum but I am not comfortable in using it as most of the topics and information's are almost useless though you can earn some bucks if you are a post booster as they pay 1k sats per post after you can reach your first 100 useful post.
