Tonight was interesting. In a matchmaking team snipers game I encountered a rogue aimbot/guest/hacker. The player showed up as another players guest and was super jumping all around the map, getting all sorts of crazy snipes and multi kills. Thinking it was the kid whose guest it was, I filed a complaint on XBL. Turns out, he was a victim of this anonymous hacker. Next game started and the aimbot was on our team- BUT with my XBL gamertag, showing he was my guest! WTF?! Again, the aimbot jumped around getting crazy snipes/multi kills etc. I quit the game. My friend was in the game, saying the player was still there, killing like crazy. Don't know what is going on, but it isn't legit, and kinda scares me that my account name was eff'd with. I also feel bad for filing a complaint against the other kid in the previous game, as he was a victim too. Who do I contact? What else can I do? [Edited on 02.12.2011 4:51 PM PST]
