Federation Policies and limit/suspend/etc.?

Hi @thisismissem, apologies if this has been asked previously.

I noticed upon looking at the IFTAS blocklists that #severity is either silence or suspend. My feeling is that this aligns with Mastodon's usages, since they adopted the format Mastodon uses for shared blocklists.

Has the T&S TF put together a recommended list of levels for federation policies, and if so, do they align with what FIRES would also publish?[...]

This doc article notes that the levels are Reject media, limit, suspend, and blocklist, with "silence" being the former name of "limit".

Right now NodeBB does a binary "if you're on the list everything is blocked" approach, but I'm looking to add some granularity.

Thanks!
