What the hell is the matter with you people? The good Doctor here is making an honest living. I hate spam as much as the rest of you, but from the sounds of it, Dr. Teeth isn't a malicious spammer like most are.
It seems that perhaps he targets his email so that only people that are likely to be genuinely interested in golfing equipment, and then he provides a reliable way to opt out of the email. Already he earns about a million points in my book over the typical spammer.
He's just doing his job. It's called MARKETING. He advertises his product in an efficient manner and tries not to intrude on other peoples' lives. So far, I think he's doing better than the companies that send me junk snail mail as well as telemarketers that call me at any hour they please. He's selling legitimate products to people he honestly thinks may have an interest in them. Based on your responses to his profession, I think he's better than the lot of you.
Cut the crap, folks. Dr. Teeth, you're all right in my book.
