User blog:Alaric Saltzman/Polls

Hi! I'm a bureaucrat from The Vampire Diaries Wiki. Last week I made a poll for our visitors so that they can vote for their favourite characters, pairings, episode etc. Some users had voted multiple times and it's not fair. The poll was made via kwiksurveys. Can you recommend another site which blocks multiple voting or suggest me what should I do? Subtract those "fake" votes and announce the results or cancel the previous poll and make a new one? Maybe on Google Docs? Thanks.
