Capabilities:
DM and Invite Blocker: Can block both direct messages and invites for all members guild-wide.
Uses the new Security Actions feature every 24 hours, so you do not have to worry about manually setting it.

Automatic spam protection: When a user sends two messages in a specific time, they get a short timeout. This stops bots, that spam messages in all Channels from succesing entirely.

You can dis- or enable all features seperately.
The entire bot is open source and privacy-orientated.
