•Keep in mind that Mumbility has been calculated since October 26th, while the bans have been given out since November 9th.
•Make sure that your browser and Mumble exhibit the same IP.
•It helps if your TF2C name and Mumble name are identical.
•We'll be taking unban requests if you can prove that you were in mumble.
•We'll need your IP and TF2C profile for anything to happen.
The dev team is actively trying to fix Mumbility bugs, it's largely a question of time.
I personally apologize for any delay in approval of these bugs.
