There have been so many "final straws" but I hope that if you still have a personal account on his terrible website, Musk promoting a German political extremist party with literal nazi ties is it. Especially looking at #journalists that for some reason seem to feel like they have to continue to maintain a personal presence there. (I understand that organizations will be the last to go, but individuals - if you have any control at all, delete your :birdsite: account.)
And no, I don't think it's worth going into "protected" mode so nobody claims your profile. I don't reserve accounts on Stormfront, and I don't have to do it on X.
