LOL
Votes can be faked easily. theymos said to discuss but no poll.
yo-blin proposed to vote by sending fixed amounts to the wallets of candidates; transfers only from verified users forum; further voice of the user is multiplied by the number of his activity.
This can cut off the spammers with referral links, users with multiply accounts, and it considers the user's rank at a forum.
It is bad option of carrying out vote? The question is rather to theymos...
