Hey guys,
I've been spending practically every free moment of my time the past few months
working on a project--and I've gotten some valuable help from the community

Why not use some sort of captcha they have to enter in addition to
selecting the item they wish to vote for. It is hard to automate reading
captcha. That combined with a cookie will reduce the amount of
