I have already explained over Discord, but to reiterate the reasoning (as there's been a lot of misinformation regarding this ban):
You purposefully took a staff member's profile picture and username and this is impersonation, which as you should know is not allowed. You do not need to be in-game to be impersonating someone as this type of impersonation can be determined over Steam (although,
most of these cases are caught in-game).
And as for unbanning, I will not be. The ban is valid and your behavior both before and after the ban has been less-than satisfactory (ex. spoiler, Discord ban here, trolling on Elysium Jailbreak, etc.)
Appeal declined.
