A few days ago, I banned a problem player permanently for directly harassing a staff member. He was given many chances, and decided that it wasn't enough.
Since then, he has made fresh accounts with F2P games while using Family Sharing with his main account to evade the bans and be an overall pain in the ass. Considering we've had persistent griefers in the past, I'm surprised that this has only started happening now.
Is there any specific way to stop players that have been permanently banned from Family Sharing to evade it?
