so...they are manually re-setting the "interaction limits" over and over again, since they are only temporary?

why not use hooks to automatically reject issue comments / PRs etc. from users that didnt go through onboarding, rather than repurposing GH features that aren't really designed for that use (and are hence in danger of being changed someday)?

GH sends the email notification to all subscribers at the moment of posting a comment. There is no cooldown or a way to unsend the notification using hooks
