Game got 3 ratings in the last hour with 0 people playing it and 0 comments.

Another LD team got 10 ratings at the end with no comments and no downloads.

Don't do this. Don't just rate games without having any impression of what they are like. PLAY THEM. Random votes help no one and ratings barely contribute to your smart rating anyway. Good comments/comment karma are what get you through the system.

Could it have been people that wanted to wait until the end to rate? maybe. I doubt that accounts for all of the votes, though.

That's all I have to say on the subject.
