Being an old grandpa not that adept at tech, I don’t know how Lemmy works. I mean, I know it’s decentralized and it’s supposed to be better than reddit, but still, how vulnerable is this platform from censors looking to block anything in here?
Are we invincible like those thepiratebay.org instances which jump up the more you try to censor them or are we basically like reddit. In other words, can I reliably access lemmy in China?
I would say the same about the entire china firewall.
Unfortunately, China’s firewall is a extremely robust technology. It is much more than just a DNS sink hole.
For example, it can block IP addresses (probably dynamically), like digital ocean or AWS. It can even block internet protocols, like TLS1.3 https://www.zdnet.com/article/china-is-now-blocking-all-encrypted-https-traffic-using-tls-1-3-and-esni/ . It can even block tor, a inernet protocol designed for anonymity and prevent censorship https://www.technologyreview.com/2012/04/04/186902/how-china-blocks-the-tor-anonymity-network/
It is truely disheartenng to see talented engineers working on this piece of oppressive technology. I imagine if they want to, it would be rather trivial to block most activitypub instance.
