The problem you guys will face is that if you remove the bot votes from iOcoin, iXCoin,Panda and Klondike there won't be much for charity.
The donations for the disqualified votes will still be going to the The Water Project, even if they don't count towards the coins.
In retrospect, don't you think you kind of limited the amount that could have been donated for this cause by limiting everyone to one vote each?
