Just because an ad isn't specifically related to gardening does not automatically mean we need to block it. The ads on the site are often based on your own searches you may have done on google and stuff like that. When I shopped for cell phones, I saw verizon ads for several days afterward.
You can turn ads completely off, if you wish. Do that through your preferences.
