Addon

Could be useful although proxies don't mean much I've never seen much of a reason to block them, people have their reasons I'm sure but the best way to ban players is always steam id. anyone can get a new ip within mins unless they buy a static ip. normally changes every hour. as for no family share that will help a lot, seen a few don't know if there's any difference in them just make sure its good(if they can even be bad?) i use serverguard so i don't ever deal with it much.

Dont use the 2nd one. It contains an "exploit" allowing people to read out the api key you saved in the data folder

I've contacted the developer of the second one. I'll let you know if he fixes it.
