Earlier quoted context omitted.
I, as a user, am still going to demand that I can join a community where of likeminded people and moderation so I don't have to deal with the overwhelming spam of the internet myself. That's the bit that a number of decentralisation projects don't get - I don't want to have messages by anyone on the whole internet forced into my view (because have you seen how much that sucks?). I want moderation if the day-to-day us…
"where it is up to the user whom they block" does not imply that you have to manually select who to block, rather it could as well mean that you are free to select block-lists (with the ability to fork them if you so wish) of your own choice rather than have the admin of your network force them on you.
I'm happy let those who want to run a community that has similar values to mine block obnoxious content for me. Far better that than Facebook or Google being the sole arbiters.
