It's such an astounding difference, that I'd love to hear what you think is so similar between "people between 30 and 40 like your product", and "Leon Kowalski from 1187 at Hunterwasser, who is 32 years old, divorced, pays alimony, has $30,000 in debt, has been arrested three times, once for felony assault, buys fetish sex toys online, and participates in white supremacy forums likes your product."
