Were those direct/"private" messages?
I'm wondering what kind of safety tools you have in mind? I've been thinking about possible chosen-3rd-party screening to help protect frequently targeted people (in both public and direct/semi-private messages). In my idea, a person could choose the level of screening they want from filtering severe abuse only all the way up to filtering out non-constructive or negative messages.
I'll spare you the full rant this time unless you want it.
