Old members shouldn't get preferential treatment if they break the rules. No one would be complaining if a new member got banned for swearing at a moderator. Sometimes people need to be made an example of in order to keep others in check.
You don't get banned for swearing at a moderator. MPOE-PR was asked to stop spamming/trolling by Maged, and rather than stopping, she swore at him. The act of insulting Maged itself didn't get her banned, it was the warning, and then lack of acknowledgement of the warning that got the ban.
I was going by what the OP posted. It's witty how people usually leave out important details when they bash the mods.
