Off the top of my head I can't recall, paywalls have been implemented for a few months now. In general when I couldn't get a NIP to work well with a monero part of the site then customized code was used. Nosmero went through a bunch of interations on how monero tipping was implemented and as features were added. Not a lot was plug-in-play.
I'll go through my diary and see what the issue was, but this is a timely inquiry as I want to spend the month going through the code and replacing ad hoc solutions with an NIP when possible. Standardizing the paywall is now on the roadmap.
Thanks for the feedback, I appreciate it.
