Do we know how many Unique accounts / Bots are in the mastoverse?

Has anyone found out how many Mastodon accounts are unique people or bots?

Is there any way to find this out?


you could crawl mastodon instances and look at public posts, but because of the nature of a federated network there’s no guarantee you see every instance (nor should there be). also, AFAIK there’s also no guarantee you can see all the users on an instance (if e.g. they only make private posts) so that would be a limitation of any crawler as well.

most likely the best we can do is look at totals from aggregations such as (that just look at the /about/more pages of known instances) and make estimates of the number of unique / non-bot users on average.
