Yes, I entered via nittr.tr, chose one of the instances, got a robot turnstile.

I was on a Windows computer where I didn't care and clicked the turnstile. It was a fake turnstile that redirected to exploit URLs of rough form 1212-12w31762.spammy-url.lol/10919023w71238123ww8128z1287z18178-12w1287wz62178612873ww682183w12.

The browser blocked them. I don't remember which instance it was.

Another instance had a completely broken search feature. Nothing had the quality of the real xcancel.com or nitter.net.
