Someone who joins for the purpose of promoting a product, service, survey, etc. They're not really here to talk about "Just Mommy" stuff. Some are easier to spot than others. They'll only have a couple of posts total, and those will be links to something totally unrelated to the board they're on ("click here for free laundry detergent!" or something). Some are sneaky. They'll post something that applies to the board they're on, but they're still just trying to get a sale.
