If you are interested (and I was curious), here is a list of the all-time most popular (i.e. followed) profiles on Mastodon (this list rotates every 5 minutes): https://getstarted.social/interest_group/all-time-most-popular/
Here's a note by the creator, @adam, who says that he did *not* scrape user profiles, but he used pre-existing lists of Mastodon users: https://mastodon.adamgeitgey.com/@adam/109313972852991428.
If you want to remove yourself from his project, here's a link to his profile, so you can contact him to ask to be removed: https://mastodon.adamgeitgey.com/@adam.
