If the screenshot is real, I'm pretty sure that Scott Adams (the cartoonist) has that Search Blacklist button applied to him. I recently tried to search for users with his name, and he wouldn't appear at all (while unverified names with 0 followers would show up).
A user called '@viennacat921' joined in August 2019 with 0 tweets and is shown in the screenshot. '@b' is pernamently suspended and '@arceus' is protected and locked with all of this being reflected in the admin dashboard.
I was surprised because I searched for users with the name "Scott Adams" and it was promoting users with 0 followers and not showing his verified account at all. This was through Tweetbot iOS.
Had to go through DuckDuckGo to find his handle.
