It's probably a good idea to keep more general, say in case we stop commenting and start displaying something in the GitHub status. So... maybe `NoViolationNotification`? Though, I'm not a fan of the the negation prefix, I'd love to find a positive way to say this. I don't know if `NotifyOfNoViolations` is any better.

I'm almost tempted to go back to `SuccessNotification` or someting.
