What to do when people forget to set the memo? Is there a refund mechanism? Or can it generate a lnurl that already has a pubkey memo embedded?
To paid relay operators:
I'm working on a concept for how service providers could add recurring LN subscriptions and I'd like your feedback.
I already drafted a spec and coded a demo for something that IMO should work with current LN tech (BOLT11 and LN Addresses).
Spec: https://oak-node.net/doc/trunk/doc/ons/ons-4.md
Demo: https://se.oak-node.net
Let me know what you think. Does it make sense? Do you see any major problems with it? Is there something I missed?
Thanks!

There is no solution now for people who forget to set the memo.
The LNURL with embedded memo would work for a one-time top-up, but won't help the user if he makes a mistake in the scheduled payment.
Now that you mention it, there might be a way to do this (only accept payments with valid memo) using HODL invoices. Adding to the list, thanks.
