Mastodon has gained 106,723 monthly active users since the end of March (when Elon bought 9.2% of Twitter's shares). 93,603 are new accounts. Overall that's a 42% increase in Mastodon's MAU.
I assume this is mastodon.social. Small compared to twitter, but it’s progress.
If these numbers are coming from more than mastodon.social, I’d be very interested in hearing about how exactly they gathered that data
