I feel like this might be a big deterrent for users that might add random friends or people online as a means of expanding their libraries instead of keeping it in their immediate family. Probably a nice side-effect from Valve's perspective.
It would definitely suck to be banned because of your young child experimenting with cheats or something along those lines.
Per-account bans would also be easily exploited by those who do want to cheat - buy a game once, make five smurf accounts, add them all to a family, and get six fresh starts for the price of one. Any loophole like that absolutely would be abused.
Maybe it would be better if it worked by a system of strikes? Like if one of the accounts that you are sharing cheats, that account gets banned and yours get a strike, this strike means you and the other accounts that use your copy are more closly and harshly monitored but you can still play, if another cheat is detected in that copy then you get a ban.
This would give breath room for parents to explain to their kids that they should not cheat without leaving that much leeway for cheaters themselves.
That would require every single game/anticheat to implement a "closely monitored" feature, and also still effectively halves the price of the game for cheaters.
Additionally, this only benefits people who share their game with cheaters - just don't do that. If you can't trust someone won't cheat with your copy of the game, they probably aren't a close family member.
Well no not really. It’s two data points. Let’s work out what is different and work out why yours sucks :)
I run mine with default apps, couch to 5k, nutracheck, YouTube, eBay, Santander, OS maps, prime video, Netflix, slack, PayPal, Uber eats, duo mobile TOTP and that’s it. No social crap.
