I received a Game Ban so you don't have to - Steam Needs Better Support When it Comes to Game Bans

Steam support has sadly never been good. It generally feels like Valve tries to have their support be as small (and powerless) as they reasonably can get away with, and they have a history of not overturning developer decisions, even from devs that they've banned due to abusive behaviour, unless it starts getting media traction. So as much as I would like to see Valve do something about it, I doubt they will, unless they're forced to.

Auto-moderation has become a problem. Especially when the store is overrun with trash and scam games and they're now letting "developers" use moderation against the people doing the moderation for them? Well done, Steam.

I really hope you can help more users with false bans. It shouldn't be your responsibility, but if not you, who else will? Steam support won't...

There's only one actual human in Steam Support who actually pays attention to the content of a support request (whose name I don't recall ATM). All the others treat you like an inconvenience at best and an enemy at worst.

im permanently banned from pixel pirates forums from using the frowning snowman emoji, once
that dev is a ban happy scam artist that tricked soo many people

Good to see that you were able to get yourself unbanned.

Did you questioned your direct contact from steam why the normal support, that is available for everyone, wrote a copy & paste answer that can be shortend as "the devs have the control about the ban feature and we don't care/it isn't our problem" and how and when this change to a real handling of such unban tickets ?
In your case you had a lot of infos that it wasn't a legitimated ban, so each human that had handled that ticket should have seen very clearly that the dev used the ban as weapon.
