Killer feature. It would be awesome to have some plugin or userscript to auto-swap the e-begging scammy link for an Archive link instead.
There is a regex replacement feature. You could build a list of known paywall domains to rewrite them to your desired paywall unblocker service.
There is the extension Bypass Paywalls Clean[1] which fetches content from archive sites and displays it on the original page.
There's Bypass Paywalls Clean (not going to link for obvious reasons).
Is asking for money for your work begging? That's interesting take.
