Your response is to ask a pirate for money back?

Bold strategy, not sure if it will pay off.

On second thought matey Smee 🦜 better keep them to get through Hormooz and maybe the Dardanelles by then. If Smee sends the spam coins surely the exchange will ask for filter compliant coins as well before crediting the pirate with any more coins of any type...

Does this mean we have to worry about UTXOs that are on Bitkeys? Because there's no open source way that I'm aware of to control them.
