Here's a tip for using the federated timeline!

If you see something you don't like or there are too many posts from a user or instance, you can click to view a user profile and choose to mute or block any user. Then, leave a note to remember why.

You can also block an entire domain.

Finally, if someone is violating our local code of conduct, you may report the account, and our moderators will decide how to handle it.

(Apologies to @ericmann for using his profile as an example.)
