invitekiller

A brutally simple, self-hostable Discord bot that deletes invite links and bans repeat offenders. Designed for myself, but released publicly in hopes that someone else will find it useful, too.

How to use

invitekiller is intended to be self-hosted, and restricted to servers that you control specifically. You could make a public bot out of it, but this is not recommended since it isn't designed or optimized for that use case, and might experience slowdowns.

As part of the setup process, make sure you give invitekiller the necessary permissions to do what it's designed for, as it will fail silently otherwise. You are expected to have working knowlege of Discord's permissions system, as well as working knowledge of how to set up a bot account on Discord. If you do not have knowledge of either, simply refer to the official Discord help articles and documentation. A quick Google search will turn up the results you seek.

To run invitekiller, you will need Python 3.5 or higher as well as discord.py rewrite. Create a file named oauth.txt that contains the bot's Discord token. Then in a terminal, run the following:

python3 -m pip install --user -U git+https://github.com/Rapptz/discord.py@rewrite
python3 invitekiller.py

As this bot is meant to be hosted on your server specifically, there is no additional configuration involved, and it will indiscriminately attempt to delete any messages that contain valid Discord invite links, as well as ban repeat offenders. If this behavior is not to your liking, you can take a look at the code and modify it as you see fit for your own uses.
