Received Active Suspension with no details | Looking for further explanation on system involved

They are a department of Microsoft, but exactly how they function, I couldn't tell you.

Since there is no other way of contacting them, there is no way to get that information at this point.

Are they a part of Microsoft, like a subordinate branch in an office somewhere? Is that office on Mars or something? Actually, are they even real at this point?

I'm not going to accept this answer, because it implies Microsoft and Xbox support is impotent. I wouldn't even be suggesting it, because it's disingenuous to everyone involved.

The current case review process was not put into place till about 2015 maybe 2016 with the new enforcement teams website prior to that the enforcement team had their own forums that they dealt with enforcement actions.

Like Paul1708 said at this point with it being past 12 months there is nothing that can be done.

2011 is a long stretch for appeal anything at all if you could not do it at that time I think there is nothing else to do at this time to ne honest with you just pick a new name and start from scratch...goodluck!

So you're telling me that Microsoft, Xbox Support, and this theoretical enforcement team are so impotent and inept as a business and service, that they have absolutely no infrastructure in place to make sure their system is working properly? Or, that they
designed this process to purposefully be as oppressive and abusive as possible to their customers?

Both possibilities seem to go against their principles and ethics as a business.
