As a most clear example, there is 93.184.220.29, DigiCert's IP to serve revocation lists. It is banned since September 29, don't ask why. This basically means that GitHub, Facebook, PayPal, SUSE and ICANN websites all are either not opening or take 20-30 secs to load, depending on the browser. Degeneracy-free indeed!
Forgive my ignorance, but does this mean that Russian internet user's browsers would not be aware of revocations? Or is there another way on this one?
Edit: obviously only mean revocations of DigiCert certs
If you give people a powerful tool, they tend to get funny ideas.
Seriously, if you look at the countries that try to ban "degenerate" activity (which itself is a matter of opinion), the list isn't all that pretty. Singapore is probably the only one that's livable, but only if you relish the idea of living in a full-on police state.
Tendency here is to quick-block-and-wait, and it is site owner who must prove, not they. "It seems like" is enough.
Btw, judge who blocked p*hub.com "didn't know it is popular".
