[quote name='Foladar']No clue about any bannings re: bing exploit, but I know there were accounts blocked due to the $1 a month from Jack's Links. If you clicked it twice, whether due to lag or because it allowed you to get a second month for a $1, it locked the account via billing until you called it in.[/QUOTE]
That sounds like it had to go through actual charges with MS though. This is just winning codes from a list of 190,000 that were set aside for a contest. I don't see them doing anything. If anything, it's the websites fault for being set up badly.
That said, I made enough to buy both Resident Evil HD ports, so I'll stop for now. If nothing's happened by tomorrow I'll grab some more.
