I was thinking about this again the other day. One way we could do this is that domain owners (e.g. owner of lightningescrow.io) creates a DNS TXT record that says which SN user they are and then any content shared from their domain would give them sats to their wallet.

This wouldn't work for medium or substack posts and things like that. It also would be tricky if the user wasn't technical.

Perhaps the simplest solution would be letting the user tell us who the sats for the post should go to.
