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. As we oppose the idea of censorship we also do not want a toxic area for our users.
Remember Mastodon is suppose to work as each instance being a subreddit that's the point of the local feed. As we do enjoy the off-topic conversation the main voice should be around Linux and technologies.
Remember you have the ability to only post to your followers then it will not show up in the local feed or even post directly to a given user within the mastodon network.
