Are imdb doing something to avoid false vote trashing of films?

Yes...they do things all the time to try to keep folks from doing such things. They recently changed the way ratings appear for films with few votes so one vote of 1 will have less affect on the displayed rating. That said, it's near impossible to know if the person actually saw the film or not. I am American and have seen films in other countries. If I rated one of them, would I deserve to be blacklisted? Also, I've seen films via links given to me on this site, to see and rate films after having them offered by the film maker..same thing...should I be blacklisted? I doubt there will ever be a way to determine if someone has seen a film.

It seems, though, some users have been locating films with few ratings, most of which are 10's and throwing on 1's to try to even the score, as odd as that sounds. So, there are two camps. Those not believing the 1 and the other not believing the bunch of 10's. Somewhere in the middle lies the true picture, in most cases. Most films, though (if not all) start out out of balance and even out over time as more votes come in. I would think most people looking would throw out the 10's and 1's and look at the middle ground. I think, also, most people looking for something to see put a minimum number of votes in their search criteria to skip over those that probably are not too accurate. I usually put to exclude those with less than 1,000 votes. The best thing for a film maker of a small film is get it seen and voted on as often as possible.
