Forgot to mention an important part of being bought in this way (if you don't already know this)
-> If you cover for regular settlement after the notice is sent to you, you are still subject to buyin as your shares will not be delivered in time. This could cause you to wind up long at a horrible price (when you probably thought you were flat). Make sure to talk with your brokerage before you cover for yourself. This unfortunately is the trader's, not the brokerage's, problem/fault - you need to know the mechanics of the market you're trading in.
