I have a wrench to throw in the works. I put my XBL account on a memory card to use at my brother's and best friend's houses. If we want to play XBL there, I just log in on their xbox's and we have at it online.
My question is this: If MS is using the serial numbers and EEPROMS to ban, then why wasn't I banned earlier in the year when I was using my XBL account on others' xboxs. Their serials aren't the same as mine. The only thing I can think of is MS is linking my EEPROM to my HDD specifically, leaving my brother's EEPROM and HDD linked seperately as well, and when I changed mine, they screwed me. In that case, I'd just need a new HDD and EEPROM, not neccesarily a new XBL account. Thoughts?
