It all depends on how you define "on the Internet." Hel is technically on the Internet, thanks to The Giant, but she's not actively involved in it, as far we know; she probably doesn't even have a Google account. Do we really have the moral or ethical duty to correct somebody on the Internet if we can't really reach them through online channels?
