So Journa & Newsie, two of Mastodon's most prominent journalism servers and home to journalists from around the world seeking safer online havens...are overseen by Mr. Jeff's entity known as "Fourth Estate."
I can't find anything solid on this Fourth Estate, which claims to be a non profit focused on press related issues.
It has a Wikipedia page, citing dead links or Fourth Estate's own website for all of its questionable claims.
Again, red flags, red flags.
