Hard topic indeed, every case is going to be probably unique and also the actions to take.
As i see the censorship runing today on Hive (wich is minimal, but still exists) in order to protect real freedom first we need to recognize what harms the values that 3speak represents. Missinformation? Hate speech? Or only pervertions known as crimes (as pedophile, rapes, etc) Because some are "easy" to judge, but what about hate speech, anti science, fake news, racism, clasism, homophobia etc? I didnt see any sexual behaviour on the platform, but being honest I didnt look for it neither.
He is speaking of dangerous activity for flagging, in general we can downvote all that other stuff normally or you can join a downvote train to downvote it as a group. Usually if its not pushing violence or something that wouldn't be covered under freedom of speech anyways, no one seems to want to stop it, we just downvote it. The more mainstream the platform gets the less batshit fake news I have been seeing, same with anti science, but itll be like any other social platform. Most of the people crying about "censorship" on other platforms are still posting the same shit on said platforms / their views they are pushing are often not covered by freedom of speech / they don't understand that a private organization doesn't owe them a plaform / etc. As you said, hard topic. I think focusing on pedophiles or extremists using the platform to push their not just illegal activities, but also unethical by most standards, or as the OP said, dangerous to the community. We don't need, nor should we be, vigelantes about this, but we can take some basic steps to try and secure ourselves, and the many children on the platform, against such users. First step is discussing it.
Well we are the Good Guys Gang, so any type of censorship that we do is righteous, unlike the government, who can't be trusted to censor individuals.
