Hello! We are excited to announce Steam Families, available today in the Steam Beta Client. Steam Families is a collection of new and existing family-related features. It replaces both Steam Family Sharing and Steam Family View, giving you a single location to manage which games your family can access and when they can play. Create a Steam Family To get started, you can create a Steam Family and then invite up to 5 family members.
What happens if my brother gets banned for cheating while playing my game?
If a family member gets banned for cheating while playing your copy of a game, you (the game owner) will also be banned in that game. Other family members are not impacted.
That kinda sucks.
