I know I'm not talking about ZPS here, but I remember when a Voting system for maps was put in, a weakness created was that the majority would always overrule and you'd get stuck in a cycle of 3 maps, the same applies to things like a vote kick, Players Who think they're ub3rl33t go andd initiate votekicks, usually anonymous against players they don't like, and although votekicks can be used to do good, alot of abuse can also come from it. Callnig an Admin is a more efficient way.
