I did get an email and an AH/trade ban last year for 14 days (I think?) because I got careless. As long as you trade set pieces for high golds/low elites, you're good.
What NOT to do:
Don't sell a silver card to a farm account for 3 million coins
Don't trade a low silver for 95 Blitz Deion
etc.
haven't received anything this year.
