Or have I missed the train on this? I know services like twitodon.com were available to find users on Mastodon that an account is following on Twitter. But it looks like with the API goofiness, those services are shut down. Is there any way to do this now?
I started to develop one tool just a few weeks before Elon announcing API access will not be free. I had to pivot my project to something similar but obviously for a niche.
I did a tool to find your Masotodon friends in Pixelfed (https://findmyfriends.online). That’s far way than the initial goal, but honestly I did it to avoid throwing my work to the trash.
