I've just updates chaos.social to mastodon version v2.4.1. You could find the release notes with new features like a delete & redraft function for toots here: https://github.com/tootsuite/mastodon/releases/tag/v2.4.1 #mastoadmin
If you're running a #mastodon instance and it has more than just your personal toots housed on it -- you are responsible for the safety and longevity of that data. People are investing time and effort into communication on your platform. You owe it to them to keep regular off-site backups, and learning how to run this bloody thing so it doesn't explode on you one day and leave you saying: "why did docker delete my database", or " my vps provider shut me down, and I've lost all my user data".
