Nothing has been officially confirmed yet, but it's been increasingly reported that the TOP #2 EOS Block Producer, main Chinese exchange ZB is keeping it's users' EOS tokens hostage spreading fake news saying that withdrawals are not possible because the EOS network is unstable.
At the same time they are reportedly using users' tokens to vote themselves for a Block Producer.
If the allegation are proved true, that this may be the biggest, the highest profile EOS Scam to date.
So now, what can be done to take them out? I have some strong feelings that some other exchanges, who do not allow EOS withdrawals, may be using similar tactics: use their users' tokens for personal gain.
