I don't know. I think I understand the viewpoint. I get emailed by random people all the time. I usually reply to them, and try to be encouraging, unless I'm super harried and it just slips through the cracks. But, as far as I can tell, none of them have really turned into anything. Usually, they end up ignoring my email. There's been dozens over the years and it probably would have been a better use of my time to ignore them.
