We dont know on whats the true motive but building up an another crypto-based forum would most likely trying out to compete with this forum.
No, man.They know competing with this forum will not work. None of the crypto forun can reacg such position ever you know. The goal of their forum is to attract more newbies in yobit, or getting new customers and promoting their shitcoin for free. Most of the cryptotalk users are people looking for earning without investment.
I will not surprise if I see their token is being huge pumped, because this way they will be able to attract more users to their forum.
