By posting inquisitive spam like this one on forums where lots of people will see the innocent looking vanity. Once some poor schmo reads the post their curiosity gets the best of them and they end up checking out the company in question. It is the hope of the poster that the subject checking out the company will end up buying the companies product without the company spending a dime in advertising.
Good luck.
Interesting theory, but with leaps like that you should be on the olympic team.
