I'm seeing a ton of expired 0.00000000 BTC invoices in BTCPay related to my Lightning Address. I'm guessing it's a Nostr thing?

Let's see what happens when I set the minimum invoice amount to 1 sat...

Looks like nostr:npub155m2k8ml8sqn8w4dhh689vdv0t2twa8dgvkpnzfggxf4wfughjsq2cdcvg doesn't apply this limit to LNURL invoices. I guess it ultimately doesn't matter.
