Mesha's source is personal experience. You're *literally* asking her to point to the messages her attackers left her.
If you don't believe that Mastodon can be dangerous, google for "Mastodon blocked instances". There are many lists of them. Then choose one or several, and look through the public posts on those servers.
Then ask yourself: if these are the public posts that anyone, not logged in, can see, what would they write in private? Imagine that they were attacking you instead.
