to be fair ( no idea in this case) there are plenty of people that don't break the rules and got bans. The rules are so wishy washy and can be interpreted in different ways. I have yet to see a rule that specifically says you can't trade cards or guidelines for such trades. There are in black and white rules against promoting of coin sales and buying which is broken hourly all over youtube which get a blind eye turned to them.. EA doing EA things.
