My local grocery store discontinued the use of plastic bags entirely. They now do a tidy trade in reusable bags at $1 a pop. Many of which are used only once.
Those fakes are a real scourge. People lose their data in addition to their money.
Very easy to spot fake listings but the platforms allow them to proliferate. I consider the platforms to be criminally culpable because of the wilful neglect.
I was considering creating a censorship free bluesky pds. The showstopper is that bluesky can cut off read access to the content firehose relay. I suspect they would do that, or be forced to do that if a true free speech platform were to emerge.
Private group chats do not tend to be encrypted. If my theory on what governments are most concerned about (disrupting alternative political organizing) holds true - they never will be allowed to be fully private.
Bluesky prioritized safe-space culture over free speech and decentralization. Interesting experiment but that's not what a Twitter replacement needs to be.
I'd encourage you to embrace full decentralization via blockchain technology. Why? Any successful tech that empowers and connects local communities becomes very politically interesting very quickly.
