Yeah, I noticed that too, Ylvalaric... :/
People could also put a link to the poll on tumblr, twitter, pretty much any social site and get tons of easy votes. That's why I thought that the public voting would take place in the updates and you comment your vote. I guess that gets rid of the anonymity of it, but it prevents cheating.
I think that since the voting is taking place like this, that there should be clear rules posted stating that posting on public sites are against the rules. Unless the staff deem it not against the rules? But I'm pretty sure that the voting is supposed to be honest and only done by the Res community.
