There should be a new user group called (Flamer) or something like it and you get into this user group if the following...
-70% or more of your posts are flames
-you generally don't post good comments even if they are not flames
you could also put a button in the corner simular to the +rep button to report flaming and if they get enough reports they get into the flamers group
one in the flamers group they will have the same restrictions as the leechers but in order to get out of the lamers group they will need to start posting helpful comments and once more than 70% of heir posts are helpfull and nice they get out of the group
