I think that in TA's hypothetical "I got banned because I sent stuff to my alt" situation the big question is what constitutes "adequate in-Game consideration". I think having a level awesome character quite plainly would, as you have put in the time to grind out the levels on someone else already.
The problem we seem to be having here is a disconnect form what people are actually being banned for and what people could hypothetically be banned for. Now I'm not saying that I agree with EA or even think these 'hypothetical' situations are stuff that they wouldn't ban you for, they are EA after all, I'm just saying that its pretty par for the course as far as MMOs are concerned.
You forget that admitting to using auctioneer in WoW is still to this day a bannable offense?
And I have personally been warned in WoW numerous times for my language, despite the fact that I never swear AT people, just in conversation, and that seems like all they're doing for offensive names and swearing so far(warning people). Unlike in, say, World of Tanks, where an offensive name can have you banned until you put in a support ticket to have it changed.
As I already stated, the dude that was banned from the first link was apparently gaming the system by using friends on the opposing faction to cheat PVP. I don't see how anyone could argue that something like that shouldn't be a bannable offense.
