Hi Plebstr, I was thinking more about the idea and I think it can be improved in this way:

1- Could have an option on Plebstr like: Allow to zap the same amount, the previous successful user you tipped, if the user you tried to send sats has no zap enabled?

If this option is marked yes, the zap goes to the previous user I zapped and a note like this is sent: Hi Bob, I tried to send you 100 sats, but as you didn't enable zaps, the 100 sats was sent to Maria.

The interesting part is that some service could use this information to release a page showing a ranking of the nostr users that could have received zaps but didn't because has not zap enabled.
