Hello! I was trying to change my username, but once I clicked "Yes, I want to change my username" it brought me back to the bottom of the page, and said that my current username was globally blocked by Phalanx.
I've looked into your account and you are not globally blocked. Please try the form again and if you're still not able to rename your account, please reach out to us via S:C so we can take a deeper look.
Edit: It happened again. I went on the Special Contacts page, and went onto the "rename your account" page. Its the same thing, and I read it again, twice, just to make sure I was doing it right. It didn't say anything about having your current username blocked globally. ;-;
