Players get banned from Halo games, including Reach, for violating Xbox Live's terms of service. The most common violations are for various forms of cheating, including network manipulation (putting your modem to stand-by mode), and also harrassing other players.
If you get banned then you can't play.
Well you can get banned in all the same ways as in Halo 3. now you get a temporary ban if you get booted or quit to much.
you get banned by modding credits instead of earning them yourself
You always get credits in halo reach until you reach inheritor, you only get banned if you get said credits illegally...
Yes but it is against rules, and you may be banned from Halo and even your own xBox.
Yes But You Will Probably Get Banned
Hacking is illegal and you will get banned.
Yes, but you will get hardcore banned!
by playing with it
Depends on the cheat but all of them will get you banned.
Usually for 10 to 30 minutes.
