I recall someone's note about feeling self conscious about sending 1 sat. Or that it could be misconstrued as being cheap. If that's all you can spare.

If you're earnest. I don't care. That 1 sat meant something to me. I'll take 1 sat from a person than some funded bot spam program. I'd rather be able to block a 10,000 sat zap from a spam attack than your 1 sat. If it comes to that.

If that's even possible.
