The only one I'm aware of was Switter. Unfortunately, it shut down months ago.

Well, considering Twitter "permanently suspended" my account because they said I violated one of the rules when I absolutely did not do that, this may not be an issue for me.

I'd love to find a platform with some integrity. Inhabited by some intelligent people.
