Mastodon is supposed to work as if each instance was a subreddit, that's the point of the local feed. While we do enjoy the off-topic conversation, the main voice should be around Linux and technologies.
Remember you have the ability to send followers-only posts - which will show up to your followers, but not in the local feed - or even to post directly to a given user within the mastodon network.
When you post something offensive, it shows up in the Local feed. Since this instance is dedicated to Linux and a Collaboration of technologies we do not tolerate obscene behavior. While we oppose the idea of censorship, we also do not want a toxic area for our users.
