Hmmm... I mean, the message I receive is very clearly from .wine...
Either way, I agree that it makes sense that .wine sends me an invoice: it's their business model to host notes and other stuff
99% sure adding sendit.nosflare.com to broadcast relay is the cause. So unless we're in a 1% edge case, I think it might make sense to mention something about this in the explanation text for broadcast relays on the relay panel. Like: "you will receive invoices from any payed relayed that the broadcast relay is broadcasting to" . Or perhaps find a broadcast relays that excludes paid relays...
In my case, the fix is easy, since I have my own broadcast relay, I can just remove it. But please, let me know if you think I may be able to help you in any way. And many thanks for your assistance. 💜
