The OP's only other reddit post says that they want to start a corporation to avoid associating their name with the game, which is a pretty big red flag to me.
"I've been developing a game for a while now, and am near ready to release it on Steam. I'd prefer it not to be associated with my name (as in I'd prefer people googling my name and future employers being unable to find out i developed this game )."
Depending on the genre, that may be a reasonable action. If I were to uncharitably assume OP submitted an adult game with rip-off characters, that would explain both OP & Valve's behaviors. If this transpired at all.
Given the tech involved and allegations I agree with the others that this is a smut game, but shielding yourself with an LLC is a smart move for anybody doing anything controversial, commercially.
ehh, I've thought about it too. It's almost recommended if you want to make adult games. Even if I don't care about employers who'd reject me for that stuff I don't want crazies harassing my family just because I wanted to make a game with penises in it.
