Блокировка/замедление Twitter (26.02.2022)

OONI published very detailed report on blocking / throttling of Twitter and other social media sites.

Twitter just got an onion site: https://twitter3e4tixl4xyajtrzo62zg5vztmjuricljdp2c5kshju4avyoid.onion/

I’m curious, are instance of the alternative front-end Nitter accessible in Russia? I think they only allow you to read, not to post.

Some of these instances have onions as well.

I suppose this is done not by TSPU but by Beeline only?

Yes, seem like so.
