Well, since I never visit those sites and I'm using the municipal iPad tonight (which is NEVER used for even suggestive or controversial websites), it isn't based on what I frequent. In fact, I think I've only been on UU on this tablet twice before.
I'm a cranky senior with a solid marriage I would never jeopardize, loudly socialist and atheist views. I visit news sites, political and historical sites. Musical sites. Gardening sites. I read media/newspapers from India, China, Mexico and England as well as the US and Canada. I read literary sites about Shakespeare, Chaucer and Machiavelli. I visit sites that have science news, and revel in the latest breakthroughs in paleontology. I write about tequila, Henry Hudson, the history of motorcycles, municipal politics and film noir.
So it's not based on my personal history. I have no interest in that sort of pap. Never have, never will. I'd rather be caught listening to rap or country music before I was caught visiting them.
As I understand it, the host for these ads can filter what sort of ads get seen. I don't want to see ads for "cougar life" or other such dreck. It will certainly discourage me from recommending UU or showing it to others if that sort of ad pops up.
