Improved Domain Block Explanation and UX

[ghost]

Pitch

The current explanation of federation blocks is:

Silence will make the account's posts invisible to anyone who isn't following them. Suspend will remove all of the account's content, media, and profile data. Use None if you just want to reject media files.

This is not the most clear. I would go for something like:

Silence a server to cause all accounts' posts from the server to be invisible to anyone not following them, both on public timelines and in notifications. Suspend a server to remove every accounts' posts, media, and profile data from the database, and prevent new accounts from the server. None is used to reject media files and reports from an instance without taking any other moderation action.

Additionally, it may be helpful to highlight or only show the explaining sentence for the currently selected type of block, and "domain block" being renamed to "server block" may be helpful for unifying the terminology used for servers across the UI.
If our draft of text is inaccurate to functionality, please do correct it, of course.

Motivation

The current explanation is a little ambiguous, and wordy explanations are especially helpful when taking strong moderation actions. Looking up documentation or asking tech friends for help is not the most helpful way to interact with moderation UI. A very similar issue was turned down in #2479, but I'm both not sure the current text does really accurately or fully reflect domain blocks - and even if it is Technically Correct as written, a little more clarity won't hurt.

This suggestion seems fine to me. Only nitpick is that the last sentence is passive unlike the previous ones. I'd say something like “Use None if you want to reject media files or reports from an instance without taking any other moderation action.”

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

@ClearlyClaire I think we may want to remove the status/wontfix label here, as we've currently several definitions of "silence" across the UI and the documentation, and none of them seem complete.

I'd been looking for a complete definition, since in my FIRES paper, I'm actually wanting to deconstruct "silence" into it's component filter parts, and I've also seen a lot of community confusion over what silence actually does.

In main (6c381f2) this message is now:

Limit will make posts from accounts at this domain invisible to anyone who isn't following them. Suspend will remove all content, media, and profile data for this domain's accounts from your server. Use None if you just want to reject media files.

So likely still needs clarification in UI — I would also argue that maybe this should just be a link to the documentation?
