Time for a crowd source plugin that relays copies of what individuals view right from the browser.

Users control what sites they want to allow it to record so no privacy worries, especially assuming the plugin is open source.

No automated crawling. The plugin does not drive the users browser to fetch things. Just whatever a user happens to actually view on their own, some percentage of those views from the activated domains gets submitted up to some archive.

Not every view, just like maybe 100 people each submit 1% of views, and maybe it's a random selection or maybe it's weighted by some feedback mechanism where the archive destination can say "Hey if the user views this particular url, I still don't have that one yet so definitely send that one if you see it rather than just applying the normal random chance"

Not sure how to protect the archive itself or it's operators.

SingleFile does the archiving fairly well.

> no privacy worries

This is harder than you might expect. Publishing these files is always risky because sites can serve you fingerprinting data, like some hidden HTML tag containing your IP and other identifiers.

oof good point

For a historical archive, the issue with this is that it could be difficult to ensure that the data being sent from users' devices wasn't modified in some way, leading to an inaccurate archival copy.

Cross-reference. When a site is archived by one client (who visited it directly), request a couple other clients to archive it (who didn’t visit it directly, instead chosen at random, to ensure the same user isn’t controlling all clients).
