It could have been, there’s nothing preventing such a network from providing a degree of anonymity by leaving your signature out of a post and adding a few increments to the distance on its onion route to obfuscate the source.
And in any case, you’d only need to make one remote friend to reach an entirely different segment of the network.
IMO, it isn’t decentralized enough. The federated model is better than centralized corporate services, of course, but it still suffers many of the same pitfalls in microcosm. We need private, encrypted friend-to-friend connections that enable friend-of-a-friend onion routing to those outside one’s personal social circle to effectively mimic how real human social networks actually work. The only middlemen we need are the friends we made along the way.
I cannot, and they can’t stand me either because I’ve deleted more bitcoin than most of them will ever see and I’ve personally killed about $5million in crypto scams before they could pull out the rug. XD
