    This includes emoji, avatars, headers, and media attachments.

Screenshot of the domain limits search + overview page in the settings panel, with the following text:

Domain limits can be used to modify how your instance handles posts, follow requests, media, and accounts from remote domains. This allows you to "fine-tune" federation with a domain without having to resort to putting a full domain block in place to cut off federation entirely. For example, you can use a domain limit to mute all accounts on a given domain except for ones people on your instance follow, and/or to mark all media from a given domain as "sensitive", etc. When you create a domain limit, it extends to all subdomains as well, so limiting 'example.com' also limits 'social.example.com'.
