There are some compelling use-cases built on #bitcoin's LightningNetwork to prevent #spam. If our memory serves the #SphinxWallet and others double as a #messaging system with the #KeySend feature, ie. the ability to send payments without an invoice.

A person can send 1 satoshi with a message. This means when two people send #messages to and fro, its effectively free (again, #LN = no fee), but spammers end up paying.

It does require all to run Lightning over Tor/I2P, though.
