If you assume basically good-faith users: why nag them? After they registered? Aren't they assuming basically good-faith authors? Why do you think people who you'd nag after they registered would copy-paste keys but not download a crack? (Your registrations are time-limited? That's very unusual for self-described "shareware". That's pretty much "commercial, but your demo nags".) You're welcome to choose whatever business model works for you, of course, but take it from me, this one's straight from the early '90s. I hope it works for your users too.
