Keep an eye on cards tied to Microsoft accounts. I had three new accounts pop up under my card on the fifth of December. I had to file a fraud report and cancel each account by calling in and explaining my situation, and that the only account I have is on prepaid cards. I was refunded fully, and the boxes tied to those accounts are permanently offline.
Again, please keep an eye for any double, unexpected, fraudulent charges for cards tied to your MS account.
