Subject: [PATCH] Detect Pleroma and Pixelfed profile links

- Re-introduce the server blacklist unchanged
- Incorporate it into the Fediverse profile regex

These two platforms sadly have a non-unique URL scheme,
so it may be better to keep the blacklist in place to filter out
all the github and codeberg URLs.
