Yeah, I suppose a nice fully featured protocol would use something decentralized, but that extension currently has them on my site. e.g. Another user made this one and I subscribe to it too: https://overmod.org/lists/view?pk=0STtY8mc3j6Pyaaf3YeKGHkcBK...

I separate mine by a bunch of categories which might be a bit complicated, but I was hoping perhaps people might not care about some of the categories https://wiki.roshangeorge.dev/w/Overmod#My_Stuff

e.g. I don't like endless repetitious "but corporations" stuff and I also don't like "but they sell your data" repetitively but maybe others want to block category A but not category B.

I think that wasn't a sound idea, though. Either people trust you to block for them as well or they don't.
