In my opinion, FMHY has turned into a search engine (they have more than 10,000 links) rather than a simple list of resources.
That is why I am planning on creating a simple and mentainable list of resources, where all of the links would be checked periodically in Virustotal and offline websites would be removed almost instantly.
Which bring me to the following question, what is the best service to host this, any suggestions(preferably open source)?
I think it would be easier, since it does not require agreement on transaction between two parties, only signing your own transaction. Anyone can fork and clone anything, and then add to their own signed version. All that is required is that you cloned from an existing trusted version and you made these changes to it. It's easy to verify.
It only requires that the user can select some release group that they trust and store their public key.
