Point in case: On Freenet it does. But I had to close down my youtube comments on my channel completely when they discovered my youtube-Account. Because it’s the clearnet where moderation sucks.
Its actually scaling, fully decentralized moderation system is how Freenet keeps communication friendly with actual pseudonymity and privacy protection: https://www.draketo.de/english/freenet/friendly-communicatio...
If the question is WHO to censor, I've always thought the solution is not at the server side but on the client side. Any platform where sensitive topics are being discussed (conspiracies for example) is going to be spammed, trolled, forum slided, etc. The solution is to have filtering on the client side take away the spam. Similar to how you have ad lists which block adsense, googleanalytics, etc. Allow ALL speech, and then filter out just the ones you want. Much better than having a tyrannical government or corrupt media or powerful tech giants do it for me.
