EA apparently needs to make some changes with their customer relations and TOS--as I read it, forum activity can lead to loss of access to your games.
I'm a little confused about the ban, because when I viewed your Battle Log profile page, it appears that you were in-game on 12/5. However, you implied on 12/6 that you were communicating with EA.

Two days ago was December 5th. *shrug* maybe I'm reading it wrong, or maybe you were still part of a team and joined automatically, whether you were present or not. You had a 0/0 record.
The other thing is the inconsistency which you refer to the post that apparently got you banned. You have been positive, 99% sure and 'can only conclude' that the post from another user--with your name in it--was why you were banned. You don't believe that you quoted the 'NBC' post.
Also, the support person you spoke with and recorded didn't seem to have much information about the specifics of the ban. Apparently, these issues need to be resolved online and not over the phone. I guess that was to show fraggotman or whoever how wrong he was--any other point to that recording?
Also, the email you posted on this thread about your 72-hour ban (which has apparently taken place) had a subject that read something like "Inappropriate content in profile". I don't know if that's the Battle Log profile which shows your latest posts on the forum or something else. That was--what, eight days before the ban? Do EA bans work like VAC bans in Steam, where they may be handed down a few days following the notice?
There seems to be much that needs to be clarified with this story, but it shouldn't distract from the main point of EA's ridiculous policy of linking forum accounts to SP games. Banning MP games for forum asshattery is--well I guess I don't play much online other than EVE and the politicking on their forums is effectively part of the game. You lose your ass, not your access.
