Hello. :) Please be civil. You are free to appeal your ban, but calling others "idiot" or "stupid" is not acceptable whatsoever. If the moderator refuses to lift your ban, then leaving multiple messages to them is not the way to go either - please move on and patiently wait out your ban in that case, or contact Staff through Special:Contact/general if you disagree with moderators' decision if you must. Although, a ban lasting merely for two hours with a legit reason is probably not quite worth for that.
