you don't need to post nasty things, so why should others have to read them?
and seeing as they are anonymous, it's not really on that anyone can post whatever they like and on one is any the wiser

if they were used for the correct reasons then i wouldn't nind, as in linking different posts together, but they aren't, so if you can either see who's posted them or have the option to either have them or not as the op, then that would stop people saying nasty things and thining they can get away with it
