I was thinking more of a browser level plugin, in which content from unverified users would be blurred out with a "unverified user - click to view content" type of system. Everything you post will be connected to your identity, so you would be liable for deepfakes and the like. You would also have an activity rating connected to your identity, so other people could see if you are posting 1 piece of content per hour, or 1000.

Maybe a personal media manager connected to the browser so all of the public content that is "signed" by you will be easily viewable by you, and if someone posts something that is not actually yours under your identity somehow, you will be easily be able to rescind the signature.

Just random shower thoughts...
