Also: That a solution looks different depending on how you use social media. Creating a very restrictive community is desirable for some, but not for those trying to get a message out for political organizing, fundraising, small business, or independent news publishers.
I saw 2 posts the other day: a white trans woman raving about how little harassment she gets, probably thanks to a server with strict blocking. And a black (cis) woman saying she gets as much abuse here as on Twitter.
