A small ULib module that automatically detects and bans people who attempt to circumvent permanent bans by creating new accounts. This is similar to Family Share blocking modules, such as this one by Timmy, but it doesn't actually check Family Sharing, just their IPs.
To install on the Workshop, simply add this to your server's workshop collection. For more information, the Garry's Mod wiki has a good tutorial on using the Steam Workshop for Dedicated Servers.
