Is this really a problem? I cannot imagine moderators deleting a post from normal participants which was 'inappropriate' without some communication about this occurring, either beforehand (eg, a warning to chill/tone it down) or afterward (eg, an explanation).
PS from 'normal participants' I exclude spammers, and blatant attempts to manipulate the forum for one's own gain, such as someone who's never been here before, register, and then immediately post 'you must see/buy/get this' type rubbish, and on being queried or found out,disappears and is never heard of again. At least under that name
