Good point @ekzyis,  the size payment probably doesn't matter.  You are correct I was refereeing to the number of invoice that might be generated.  Now one at least have to have an account to generator an invoice or a LN Node. vs in the future just a web browser. Maybe a time cool down based on IP address would be a easy check.

As always this is hypothetical and may never been a real issue.

I don't understand what the issue is with "spamming" the SN node with 1 sat payments from a technical perspective.

Is it about creating a lot of 1 sat invoices (and never paying them - but then I guess the amount doesn't matter) or about actually paying a lot of 1 sat invoices?

But in both cases I would still be confused.

What is the problem with this "spam"?
