Today, we permanently banned 90,000 smurf accounts that have been active over the last few months. Smurf accounts are alternate accounts used by players to avoid playing at the correct MMR, to abandon games, to cheat, to grief, or to otherwise be toxic without consequence. Additionally, we have traced every single one of these smurf accounts back to its main account.
I always play on my own account there, shared accounts are usually when people want to play paid games they don’t own
Yeah idk maybe contact Valve support, I’ve had relatively good experiences with them regarding VR stuff.
