Did they try to become members just to e-mail Scott,
Yes, some people do that (and I'm sure I am not alone). They want to ask questions about some mountain, canyon, feature, or whatever. Sometimes it's just a hiker/climber. Sometimes it is the park service looking for information and sometimes search and rescue looking. At least twice it has been a real emergency, such as when Search and Rescue didn't know where a place was and asked me to help explain where it was (and no I didn't have an SP page on it), though that was a few years ago. Luckily if it is an emergency, people are inclined to leave phone numbers.
