I have been modding BO2 accounts for free for the past couple weeks and the last 2 days almost every account got banned (Not console, not PSID, but banned from specifically playing BO2)
I was looking around the forums and noticed lots of people are saying the same thing. I think it's safe to say stay away for now, or if any developers of RTM/eboots can look into this that would be great.
Please post below if you have been noticing the same thing.
