So as far as I can tell, my Bungie Name got changed to well, this, when I was first participating in the October Marathon Closed Technical Test. I thought at that time it was a Marathon specific bug, but upon logging in to my account today for the first time in a while, it's still Redacted and I can't change it back.
Hello there,
Thank you for reaching out.
We understand your Bungie Name was changed to Redacted. If your name was changed for you, this means it was in violation of the [url=https://www.bungie.net/7/en/Legal/CodeOfConduct]Code of Conduct[/url].
If you have a name change available, then you can use it to change your name, provided the new name passes inspection from the name filter. If you have no name change available, then unfortunately, you'll be stuck with the name you currently have.
