I talked about this on my Twitter already, but it's especially important to keep hammering in this one major point: this policy applies to the accounts of people who are deceased. Other social media sites have protocols to deal with the dead, and Twitter does not.
Shon Howell was a good friend of mine. He's better known as King Cheetah, a prolific furry artist that had been active since the 90s. In early 2019, he died from cancer, leaving all of his art and social media accounts abandoned.
Once this policy was announced the other day, I realized what that meant. So I went back to check Shon's Twitter, and...
Thankfully, I do have a huge archive of all of his work, and I'm in the process of tracking down and preserving anything that's left. But keep in mind, especially if you're an artist and use Twitter as your main platform: go somewhere else. Make sure your work is elsewhere. Make sure you can be contacted elsewhere. Twitter clearly has no concern about archiving your posts anymore because Elon fucked things up and seems to be invested in continuing to make it worse.
