"People on Mastodon and the Fediverse tend to be #privacy conscious. So there are limits - both in the API and the culture - as to what is acceptable.
Some people don't share their #socialgraph. That is, it is impossible to see who follows them or who they follow.
Users can choose to opt-in or -out of publicly sharing their social graph. They remain in control of their privacy.
And that's OK! People should be able to set limits on what others can do with their data."
