Blossom is soo stupid.... It externalizes the "freedom" to users while concentrating the risk on operators. As operator of a blossom server you are responsible for everything uploaded to your server - CSAM, copyrighted content, revenge porn, terrorist material, and any other illegal content in your jurisdiction. You are forced to actively monitor what you're hosting otherwise you can easily get in trouble - facing criminal investigations, lawsuits, server seizures, and financial ruin. One bad upload can destroy your life.

It's basically like running a Tor hidden service on the clearnet - all the liability of hosting anonymous content, none of the protection.

Relays have a very similar problem, but at least the content is somewhat obfuscated through WebSocket - you need a Nostr client to easily browse what's there. With Blossom, you just need a URL and everyone on the planet with a browser can open it, including law enforcement. It's trivially easy for authorities to find illegal content on your server. You're basically painting a target on yourself.
