Thanks for the mention, I'd not heard of Mastodon before, and am new to the idea of distributed social networking. It sounds appealing on the surface, but I'm trying to understand its level of privacy/security for user data. (This may be my fundamental lack of understanding of the distributed system). They say, e.g. your data isn't harvested for ad revenue -- how does one verify this? Is the data encrypted?
