What is it

Two tools in one:

Gate - prevents unverified players from leaving the spawn area using teleport containment, and forces them into adventure mode so they can't break or place anything while inside.

Jail - locks a player into an exploration-proof cell, forced into adventure mode, with an optional sentence length.

Who is it for

Server operators for small public (or private, if your friends are naughty) non whitelisted servers (it works as an ingame whitelist ofsorts).

How does it work

The mod can automatically teleport unverified/jailed players back to the set location and set them to adventure mode so they can't cause any damage. And release them back into survival once they are verified/served their sentence duration
