whether they receive a payment for their signature? Is it correct rate from OP?
That is a question that only participants are able to answer.
Plus, Yobit was known as a scam exchange. His official bttalk (last active 28 February 2018 - one year ago) account was red tagged. There is no any reason be in any other list except in scam accusation.
Yobit is shady as hell, scam accusations everywhere but they got solve after days/weeks/months etc. IMO but still I will not use them anymore.
And about the listing, I guess it will still remain in the list as it's a campaign that still accept participants. And besides, scams are not moderated here, so users are pretty aware of their behaviour so it's their choice
but forum's mod/admin/DT should do about that IMOPardon us for discussing this matter on this thread OP.
