Polls are generally not a good idea. The problem with wikia's polls, is that votes are counted based on either account name or IP address. The ramifications of this is that unregistered users will still be able to vote on polls, and could potentially vote multiple times in fact.

This would allow the opportunity for some to exploit the polls to influence prices. I've been using polls until now simply to gauge the general opinion on things related to the wiki, but I've refrained from using them for more important things for this reason.
