Why I Got Banned "Something you all should know"

So after talking to EA Support I found out that trading a card that is higher value for a low value card is considered "FARMING" Which Yes I did Trade a High Value Card on the same console to my eight year old sons account to help him with his team for solo games / challenges. I didn't think there was anything wrong with that but wow was I ever wrong. The card I got was from purchasing in store packs "Extra Money to EA" but apparently this is one greedy company that can and will ban you for even trading which takes a card and turns it into a NAT? So apparently farming cards to turn them into NAT's is really bad because you can only get training for value but I guess trade enough and man you have loads of training rolls. So after this I told EA to Stick it and I completely deleted any and all game content that's related to this company. Not good business by any means. There terms and conditions should really enforce a lot of you tubers accounts but that's never going to happen. So just wanted to give everyone a heads up on trading cards as that is considered farming. Speaking of which... Think I will stick to Farming Simulator.
