I thought the same thing. What's if unkwnown peoples vote or if some people vote extreme tiers just to change te results... But even if other people votes, they can still vote only one time since it's limited to one time per IP adress.
I think we should just keep both thread explaination and strawpoll and follow the main tendency to decide tier after that (with more importance to text from our firend than wreid isolated votes, far from actual thoughts of our little community.
In other words, like we said earlier, it's just a tiering for fun. We should not bother too much about that and about false votes. 1 vote will not make a big difference anyway, too much votes will be obvious since we are not that much here.
