Screenshot of the blocking interface in mastodon with the following text: Block user? @apod@botsin.space They can see that they're blocked. They can't see your posts and you won't see theirs. You won't see posts that mention them. They can't mention or follow you. We will ask the server botsin.space to respect your decision. However, compliance is not guaranteed since some servers may handle blocks differently. Public posts may still be visible to non-logged-in users.
