> ... where people feel safe ...
This is the problem. You can make people "feel" safe but you can't actually make them safe. The 'safety' provided by centrailzed platforms is an illusion. I can go on any platform, sign up and post horrible things. Sure my account will get deleted, but it will be too late. Fortunately, the danger is mostly an illusion too. No one can physically harm you over the internet. Sticks and stones, etc. If your mental state is really so fragile that you can't handle any criticism, you need to seek help.
Doxxing is a real problem. The only protection for that is taking privacy and anonymity seriously and YOU are the only person that can realistically do that. No rule, law or policeman can prevent you from sharing your personal information. It is completely brain dead to use your real name on public forums (including Facebook, Twitter and Nostr) and still expect to retain privacy. When you put your information out there, you become a public figure and lose both practical and legal privacy protections. I always hear people saying things like "oh it's all out there anyway" or "the government already knows everything." First, those are bullshit. Second, you're not improving matters by being lazy. There are real steps you can take that will make you much safer. If you would rather make up excuses than learn, that's your problem.
