"So that we can continue to maintain the integrity of the WorldPerks program, we will investigate all accounts that we believe violate the WorldPerks terms and conditions, our Contract of Carriage or fare tariffs. This includes hidden-city routing, back-to-back ticketing, point-beyond ticketing, throw-away ticketing, and violation of WorldClubs membership rules. Accounts with infractions will be subject to appropriate penalties or deductions, including but not limited to revocation of Elite status, termination of account and forfeiture of miles."
All they do is not credit the return miles of your trip, since you did not fly them. Now if you did it every day it might be another thing, but I do it every now and then and have not had any issues.
