My knee-jerk response was to think this was a BS move, but some people take achievements seriously. People using trainers to get achievements has an effect on how they look in MP, does it not?

I think banning is a little harsh, but I think that people who hack to get achievements should have their achievements permanently revoked.


EDIT: While some might think achievements are meaningless, obviously they mean something to some people. Having them be sullied by this really bothers those people. If achievements are pointless, aren't ladders rankings in MP? Don't people take that quite seriously as well? Should they not?
