Polls have a place. Best photo of the week on the photomode forums. A way for moderators to find a preference from users. It is not way for someone to ask, "which car do you like best?" I agree with Famine, these are not what the forum is for. As for what can be done about it, it would have to be going back to the approval-of-every-new-thread mode of operation, loading up the mods to the point of not having a life. You can see how someone would build a tournament of polls, each poll having 3 or 4 cars, "which is best?" and then advancing the winners through brackets till he had the absolute best car in GT4, based on responses from knowledgable users. (That's us.)
Not being a mod, or even wanting to be, ever, I can't come up with anything more useful than this to contribute. Does that make this post less useful than the poll in the first place? Perhaps, but then again, maybe some 12-year-old who finally got his own computer the privacy of his own room, will see this and understand that polling because you can is not necessarily the way to win friends and influence people.
Maybe we should post a poll asking how to deal with useless pollsters? Vote for ignore, ban, torture, maim, or decapitate.
Says the guy with the FOUR urinal polls.
