It's more like "provenance" of content. I broadcast my accountability of "myblog.com/posts/...", but would disavow "myblog.com/posts/.../#comments"

There's some ways of like "nofollow", but nothing systematic, and no "protocol" for disavowing paths, uploads, or fragments.

Back in the slashdot days, I thought of "blogs are the stationary of the internet", a way to more authoritatively declare that the content was yours... but interop is hard and unprofitable so walled gardens became the norm.

We just haven't had the benefit or forcing function which encourages a solution to "that stuff over there is less trusted than my stuff over here".

Maybe we're at the point where hosts of any kind MUST be responsible (or accountable) for any content originating from their domain? It kills indie/anonymous hosting, but puts a fine "KYC" point on distributing "evil" stuff on the internet?
