Yobit is a famous scam exchange with an extremely dubious reputation, I am sure if you delve deeper you can find much more evidence of such frauds.
So many mates has complained of Yobit on this forum a lot, but funny enough, I have never experienced anything of such with them before leaving, I left Yobit just because I found a better exchange, so if I say I do understand what people are saying, I must confess I dont.
I want to be careful that it is not just the trend people like to follow and those who are not scammed will even claim they are scammed, if Yobit is that a bad exchange, why are they still fully functioning with lost of things I have read, while I still see so many people at the same time saying positive things about them. I understand they have lots of shitty project but to say Yobit directly scammed, I really dont know.
