No. Others have authority to make decisions as well as they have been named staff moderators, super moderators and administrators. Your son must have been accused of a serious infraction and that was the reason for the ban. If you want to discuss why the ban was given then PM the mods and/or Jordan. The method you have chosen will likely get you:
A) A reprimand
B) A serious infraction
C) A ban.
Also, attacking the moderators for trying to keep the site running properly isn't a bright idea either.
