"Adult-Oriented Online Social Networking Operation Settles FTC Charges; Unwitting Consumers Pelted With Sexually Graphic Pop-Ups"
"According to the FTC, AdultFriendFinder.com, which touts itself as “The World’s Largest Sex & Swingers Personal Community,” and its affiliates use pop-up ads to drive traffic to its Web sites. Some of the ads have included graphic depictions of sexual behavior, exposing consumers, including children, to sexually explicit images. Such ads were displayed to consumers who were searching online using terms such as “flowers,” “travel,” and “vacations.” In some cases, defendant’s sexually explicit ads were distributed using spyware and adware."
The price of dealing with Zango, I suspect.
