- To block users: when you go to someone’s profile there’s a 🚫 button to block them. It’s next to the “Follow” button, below their name.
- To block magazines/communities: the 🚫 (block) button is next to the Subscribe button in the sidebar. On mobile the sidebar gets moved to the bottom of the page, so you have to scroll down a ways to see it.
I think you’re right. There’s a “Blocked Domains” section to manage blocked hosts in Settings but I don’t see a UI to add domains to it yet. (It’s also unclear if it’d be for blocking instances, link posts, or both.)
