I'd say there's a strong correlation between willingness-to-pay for Pinterest and being a power user on Pinterest. As such, chances are, you're a power-user, and you (or at least your power-user peers) are generating way above-average ad revenues. Not only that, but due to your willingness-to-pay for things online, you're also a particular niche within the poweruser group. i.e., a person 1) with money 2) of age, card-holding, ability to pay 3) willing to pay for things etc... you're an ideal e-commerce customer, and thereby an ideal advertising-target that also generates more ad revenue than the average. In short, to replace you, you'd probably have to pay substantially more than the average. The more typical pinterest user may only scarcely visit, be quite unwilling to pay anything, and generates a lot less than $9.
