Add user warnings based on servers from FediCheck

[rabble]

FediCheck from IFTAS has a database of labels for Fediverse servers which have been defederated for some reason. These provide a good set of content warnings we can apply to users who come through the mostr.pub gateway from those servers.

Something like: This user is on a fediverse server which is known to contain: spam, harassment, sexual material

That way we can auto label the really bad content from users based on their server… this should really cut down on hate speech and other stuff coming from mostr.

In order to impliment this we’ll need to look at users nip05, check that server against the FediCheck list, and create a report from reportinator for that user based on their fediverse server.
