I just went down to the front door to go to work, and found a small business card pushed through it. This card turned out to be paper spam, and it started with the words ‘HELP! Our natural organic healthcare business is exploding!’.
It was, of course, inviting me to take part in a dubious business opportunity. But reading the first two lines I couldn't help thinking that what they wanted was for me to call a fire engine, or possibly a bomb squad :-)
(And no URL with further information, either. Just a phone number.)
It certainly seems pretty unlikely to me that they have a genuinely useful product of any kind. However, it doesn't follow that they're quacks: it seems at least as likely that they don't have a product at all and the "healthcare business" is a front for some sort of pyramid scam, which would make them common-or-garden frauds before even getting as far as the medical quackery...
[1] that initially came out as "watchdocs", which was pleasantly apposite.
