KMS is a bot that deletes old messages in text channels on a rolling basis. Pinned messages are kept. 

Example usage:
- @kms 2d
- @kms 12h
- @kms 5m
- @kms stop

If you wanna run your own instance of KMS, source code and instructions can be found here: https://github.com/internetisgone/kms-bot

kms might not be able to join new servers until it is verified (discord sets a 100 server cap for unverified bots). pls consider self-hosting in the mean time

Open source bot that deletes old messages on a rolling basis.
