You could be considered "affiliated" by accepting payment for advertising the service.
No, it's not the kind of affiliation you're thinking about.
Affiliation with a company or a service means you are taking a commission from a part of their earnings. It does not mean the money that they pay for marketing. Just think about it. These websites that have ads on them, aren't affiliated with the companies in the ads. They just paid some ad broker to put them on other peoples' websites.
