Hey, The bans were issued to people trying to use an exploit that uses the min/max function in Windows. The full fix for the exploid is expected to go live with the Dec. 7th patch. For now, there is a stopgap measure that will kick you to orbit with a Rutabaga error if you try to use the exploit. Unfortunately, this has a side effect that it will sometimes also give a Rutabaga error code when you alt-tab out of the game. If you get enough error codes in matchmade activities you could get a temporary suspension or restriction. Therefore if you need to alt-tab out, try to do so when you are not in or launching into matchmade activities.
