Temporarily suspended from communications twice for the same thing

Hello, I've read your question, and I believe I understand your position. The Xbox Ambassadors are here to help.

I myself avoid playing online multiplayer with communication enabled for the same reason. No, I've never had a ban, and perhaps that is how I've gotten there. When I do play with random players on multiplayer, I will hear their banter, but I do not engage
in it. Might I suggest taking a break from communications while gaming. To me, gaming is more important than communicating with others that are playing the same game while I'm engaged in playing said game.

I hope this helps.

it's possible that if you were in a game with more than 2 players more than one it would report you

Perhaps you were reported by several people, just at different times? That's why you received another ban? Either way the forums can not help you with bans/suspensions because it's an enforcement issue and they don't monitor the forums.

How do I submit a Case Review?
Submitting a Case Review is easy, and can be accomplished in several steps:

1. Sign in to enforcement.xbox.com with the account that received the enforcement action and select the large box with an
   orange hammer icon, or visit your
   Enforcement History.
2. Find the enforcement action that you wish to have reviewed, and select
   Apply for Review.
3. Read the Case Review Terms of Use and agree by clicking the checkbox and selecting
   Agree.
4. If you are already eligible for a Case Review, select the green arrow icon. If you are not yet eligible, you will be presented with a short questionnaire. These questions help gauge your understanding of the Code of Conduct and associated
   policies. Upon successful completion of the questionnaire, select the green arrow icon.
5. Provide any details (up to 500 characters) regarding the enforcement action that may help XBLPET conduct a more complete investigation. This may include context around the activity or content that received enforcement, information about your game
   activity, or any other facts that you believe are worth noting. When complete, select
   Submit.

After submitting, an Xbox Live Policy & Enforcement agent will begin a thorough review of the enforcement action. This includes reviewing available data and re-examining evidence that contributed to the enforcement, taking into account
any new details that you have provided.

You would have to go through
