Hey mate.
I know what it's like to be annoyed when you don't think something is right. But you do have the right to appeal the infractions/warnings you get. You can report it here:

A Super Moderator will look into your infractions and warnings you post here. If an infraction was given by a Super Moderator it will be looked into by a different Super Moderator.
The abbreviation you pointed out is actually considered swearing, swearing abbreviations are not allowed and warnings and infractions will stand for that type of thing.
Bear in mind that infractions are warnings for a ban, so you're not actually being punished as such, just warned. The infraction system is just a convenient way to track user's warnings basically.
Warning infractions are different, they don't go against you as much as infractions do, they're not as severe.
All your infractions and warnings expire eventually.
If you wish to take a leave, you can do so, whatever makes you comfortable. :)
