Nah, banned games can't be family shared.
Definitely not an IP ban; in fact that's one of the things that would work in my favor in any appeal, the fact that the ban took place the only time my account played the game from an IP in China.
Of course they could just assume I'm a lying sack of crap, and stupid too, thinking I could avoid a ban by cheating over VPN... even though still using the same Steam account.
Valve is the only party that knows for a fact my account was hijacked and that I wasn't cheating, but they refuse to help thus far, so sounds like I'm screwed. Bluehole washed their hands of me too; said they have no control over it (yeah right) and directed me to BattlEye. Had already contacted them too, but no response yet.
