Do you know what's really funny?
Those guys are not shilling for Yobit! Those are some other species of scammers altogether!
I stand corrected, you are right! Those are not really Yobit shills and that's irony, their userbase is first subjected to various pump and dump schemes/ investbox opportunities via non-existent tokens, accounts and withdrawal freezes by the exchange itself and then those same people are being scammed again by Yobit admin imposters on Twitter...lol they can't catch a break.
Given all the shady practices i won't be surprised if those fake Yobit admin accounts are not actually controlled/operated by Yobit themselves, call it a side operation (even though it's nearly impossible to prove).
