The whole issue, does not look very trustworthy (see the answer I got for my ticketon the first page of this thread), nevertheless I would avoid fuding Mintpal without having hard evidence. BCT has lost 20k votes, but these votes were not added to any other coin, neither none of BCT supporters has claimed he/she sent that money to buy votes.
Consider to that the BTC refund should have only deleted the votes by 7000, not 20000. They are claiming that 13k of the votes were all from fake accounts. Yet they have had this claim on their voting page for a long time:
"only registered users with a trade history are permitted to vote for coins"
So which is it? Fake accounts or not? Or is it being identified by IP addresses sharing multiple accounts? They have yet to provide any information that would suggest they are willingly being transparent about their process. It reeks of deception.
I doubt they will provide more concrete info that is true i don't belive it myself also but htey will just repeat the same over and over or ignore us totaly.
