Every single sim site that I'm a member of have these ads of half naked women.  Do the owners of sim sites have some control over what ads are shown?

AquariusAgate11, like the majority of sites, we're using AdSense. Ads are chosen by Google personally for each user depending on his google search queries and his emails in google mailbox for better targeting. Getting such ads means that you or someone else who used your computer (tablet, smartphone) was searching for half-naked women. Or if you have "gray" IP, this could be someone from your network who shares the real IP with you.

I see. My brother likes that kind of stuff but it's been years since he last used my computer. Strange that its showing up now.... Thanks for the response Angel.

I've seen some of the ads and they are for different games...I think one is called evony or evoy or something like that.  Some are even tied into the games on facebook.
