Players evading bans through Family Sharing.

[DetectDefective]

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?

Ban their IP Address.

Ban their IP Address.

ULX isn't logging IPs any more, neither are the general Garry's Mod logs, and even then, a dynamic IP sort of ruins it.

You can search for Cobalt's commands in the release section. It has a dban function which logs disconnected players' IPs

You might need to block part of the subnet at the firewall, assuming you have access to the firewall config.  I've unfortunately had to do that a few times to effectively ban IP hoppers.

This is definitely a complicated issue. You can detect if an account is being shared via the Steam API, but that requires much more setup work (to retrieve the API key) than we can reasonably expect most ULX users to put forth.

I almost feel like you could make this a feature, but off by default, enableable by dropping an API key into an XGUI text entry and ticking a box. Document it, give a small little info box on how to do it...
If I could figure out xlib, I'd write a module for it.

I want to point out that this script will only kick the player if he is banned on the account he owns the game on. Players would still be able to evade bans if they don't play on their main account.

Good point. You'd also have to modify the ban function itself to ban the parent account along with the lent-to account.
