Due to the way I2P works, it's harder to block than Tor. It even works in China. We even had a Chinese "chan" board for a while, but it's gone now. R.I.P. Walled City...

Telegram was always a honeypot too, this was evident by the fact that they required a phone number for signup.

Peer-to-Peer and Dark-Web chat apps with algorithmically generated user IDs that are not tied to an email, phone number, or anything else, are the way.

SimpleX, Session, Briar, and Tox are some good ones. (Careful with tox, it's true peer-to-peer, so it reveals your IP to people you chat with)

Twitter / "X" is an American site, hosted in America, operating under American jurisdiction and American law.

EU law and opinions should be completely disregarded.

Serious question. Are you the guy who probed around in Foxdick Chan's server a couple years ago?

In retrospect, I should have made him much fatter...
