Its a Joke, xbox say there making the service online safer and more fun but where's the fun in wrongly banning people and leaving the people that use this hunk of junk, every single day when I'm at friends or family watching them play SnD someone is running
God mode, I made a list, nothing has been done, we report them, nothing, guess XBL ban legit players for cheating and don't ban the modders basically saying yeah its fine to use this, this is fair, how is it fun and fair when your shooting someone who doesn't
die, where is the logic on that, you call that fun, you don't even make an attempt to sort your games out and you've got the cheek to wrongly ban me and say your making XBL a safer place.

I got a ban for telling someone they are **** bcuz they called me a noob and now i got communication ban

I feel your pain. I got ban from someone harrassing me, i called him a hillbilly and blocked him. Two days later, communication ban. Two days after that, xbox live ban for 3 weeks for harassment, when I couldnt even communicate. Appealed it, “decision upheld".
Lol its a joke. Anyone can report you nonstop(which I presume was happening from the harrassing guy) and they will ban you just for fun.
