We can't do anything when participating in their campaign, because they reserve the right to change any rules at the end of bounty, and we have to accept it before joining. But for Vidy, they have listed on Gate, a large exchange this time, and maybe binance next if they wing the community vote. But I don't think a project scammed community like this can win the vote.
They have the right to change any rules but within reasonable limits, they blame the rules for covering the scammers face behind the mask. Although listed on any top market, in truth they are still scammers and nothing more than that.
