However, there are many other reasons for which resolver operators filter 
responses, ranging from security to parental controls. It would IMHO make sense 
if the mechanism allowed these resolvers to offer an explanatory link too, 
which could point to Lumen-like databases focusing on other things than legal 
blocking. I have not discussed this with any of them, but it does not seem 
impossible that blocklist providers could set up a service of this kind for the 
domains they add to their blocklists, though there is a problem of blocklist 
confidentiality that would need to be addressed. It would then be up to 
browsers to decide whether they trust those blocklist providers (databases) 
enough to show the link.
 
Also, this would not require any particular lexicon or reason in the EDE 
message - only the JSON fields necessary to build the link. In fact, the 
"incident ID" could be pretty generic and represent a database-specific code 
for the filtering reason which would not require any IANA registry. The only 
registry necessary is the one for databases.
