i created a bot on twitter @FBPE_bot to help with the stopbrexit campaign. So I am not so keen to totally dismiss them. They can have a part to play, but maybe we need to create a parallel reward system for them to avoid people simply gaming the system and up-voting everything.

It seems odd that every account has unlimited up votes, maybe this can be limited and additional upvotes have to be purchased (with higher score users having more votes etc)
