Imagine if someone made 4chan but ipfs. All threads are hosted by the site users and the thread dies when no one has it open anymore. Sounds dangerous but pretty dope
There's a couple of attempts at decentralized 4chan clones that you can probably google whitepapers for (keyword: decentralized imageboard) but no name has really stuck. Beckons asking why they keep failing.
I searched for that once and found a GitHub to web3chan and something else I forget the name of. I don't really expect em to pick up traction but I couldn't find one that worked
From a google search and memory: There's nntpchan, diboard, openchan, Fchan (this one is federated on ActivityPub (official instance dead (active instance: https://usagi.reisen)))
