Clicksor is displaying adult ads when I told it not to. Help!

I run an online directory site, and a number of other sites which do not display adult content, and are aimed at all audiences. My arcade site is coming soon and that will be aimed at children who enjoy flash games.
Problem is, Clicksor is displaying pornographic adverts when I said not to display adult adverts on my sites. Why is this? I do not want to run a site aimed for children and then throw porn in their faces.
Please help. Thanks.
