I should also point out that you seem to misunderstand what an Ad Hominem attack is. If you insult someone in the middle of discourse, it is an insult, not an Ad Hominem. An Ad Hominem only occurs when you attempt to use the insult to somehow attack your opponent's argument (i.e. "You can't believe what he says because he's a moron.").

You may not classify personal attacks as Ad Hominem but they do nothing to add to the Logical Validity of the argument (aslo are against forum rules) so essentially they are just as fallacious.
