I think there may be ways to implement cost of engagement in the future. For trolls/bots/etc. to continue to capture your engagement with them.

If someone is 💩 coining in your replies perhaps posting a ⚡️ invoice that must be paid for them to be unblocked. Until then they are blocked and will not receive your engagement. They will be just voicing to the ether (pun intended) at that point.
