Spam protection, how? Plagiarism/copyright protection how? Or are we exploring anything goes? Anything goes opens the door to illegal content which opens the door to liability. Limited liability is not immune to liability. Directors are still vulnerable.
I understood the idea behind blacklists. I am not pro-censorship, but I also hate when a few ruin it for the many (like we saw with the endless hate spam recently, which was crashing some/a lot of people's feed).
Yeah, I usually read those hidden posts. I also disagree with being punished for up-voting someone with hidden content. My vote, my choice, no?
What you have described would be closer to decentralization. Some people had way too much power and their treatment of people was abhorrent.
