What motivation I would have to do this?
Discussion
In Damus now (probably Test Flight only) the top zap gets pinned to the top of the the replies of a note.
I can pay the person who posted a note to have my zap show on their note as the pinned reply. The owner of the note can use the sats they got paid for that zap + 1 more sat to outbid that pinned zap.
Ultimately, there may end up being too many edge cases and weird unintended consequences that this might not last long. But it could be interesting to see how it plays out.
