Famous to who though and how famous? I recently clicked through to a profile of someone I had never heard of and they had 5m+ followers. This isn't a "look how out of touch I am with pop culture" humblebrag they were just from a different part of the world, famous in a language I don't speak.

And maybe not too similar but the mayor of my city only has a couple tens of thousands of followers but is definitely known by everyone who lives in it and yes has a blue check.

How famous is famous enough isn't a question with an obvious, or single answer.
