I have proof that Xbox live enforcement did not take action against mutiple individuals,...

Yes report block and notate; info. I advise playing with a broader source of individuals. Are you egging them on. I would not engage if they start arguing. Usually no one just sends reports unless they feel some sort of way. Possibly embarrassed or something
else.

You'll be able to find some assistance at support.xbox.com where someone will be able to assist you with your current case 😀

Hi,

I’m sorry to hear that you’ve had a bad experience. Don’t reply to them, report them and their comments. Report on their profiles through xbox. Block them and under no circumstances, reply to them.

To add to what the others have said there is a setting that would allow you to receive messages only from people currently on your friends list.

This would prevent you from receiving any messages from these players.

We in the forums or Support will not be able to assist with enforcement actions.

When you report someone the enforcment team investigates, the action taken will not be immediatly depening on the severity of the offence. You will also not be informed if any action was taken against other accounts.

As for the mass reporting have a look at this. As taken from the enforcement website.

Will I get banned just because I received complaints?

No. A common misconception is that a certain number of reports will result in an automatic suspension. According to the myth, even if you haven’t done anything wrong someone can get you suspended by encouraging
players to file many complaints. This is completely untrue.

XBLPET investigates complaints and takes each report into consideration when making an enforcement decision, but a certain volume or frequency of complaints doesn’t guarantee a suspension. We take an evidence-based
approach to enforcement and take numerous factors into account when considering issuing a suspension. The context around the content or activity is particularly essential and drives our decision-making process. Simply put, there is no magic formula that instantly
results in a suspension.

Despite what some may claim, XBLPET will never ever ban anyone “for no reason”. Suspensions alwaysoccur as a result of a specific Code of Conduct violation.
