The site's guidelines explicitly prohibit promotion of "any of the following product categories: gambling, tobacco, dairy, firearms, prescription drugs, or gasoline" and no prizes can be offered that include "alcohol, tobacco, dairy, firearms, or prescription drugs."
At first glance, it seems kind of crazy. Guns, drugs and milk? How did milk get on that list?
That's exactly what the Center for Consumer Freedom wanted to know. And, after CCF managed to drum up some media attention on the subject, Facebook answered. The company "initially banned dairy promotions due to individual state laws that impose penalties for distributing dairy at a discounted rate," it explained to CCF in a statement.
Nevertheless, Facebook will now reconsider and clarify its dairy policy. "We're all big fans of strong bones at Facebook," the company said.
The Center for Consumer Freedom said it planned to thank the company by sending a cheese basket to headquarters.
