I'll gladly tell you a second time, but what Kawaiicrush said is basically correct. There is a group of people that run hundreds of accounts each. Besides using these accounts t up vote themselves, they also use these accounts to flag people to a negative rep, like me, who then have to buy up votes from the same group of people to get their rep above 0 again. Do not up vote me as they may retaliate. Greetings!
