PotaJoinGate

A cross-server join-gating and verification bot designed to prevent bot accounts from joining your server. Just add the bot and let it run, no setup required!

The bot uses various factors such as account age and profile picture to detect suspicious users. When a suspicious user is detected, it DMs them a simple captcha to complete and kicks them from the server. They can only rejoin once the captcha is complete.

If someone has verified on one server, they'll automatically be pre-verified on any server that uses PotaJoinGate, meaning you never have to verify more than once!

There are no settings to configure and no roles or channels to make. To quote Todd Howard, it just works.
