Kongregate has the same problem, many times even though there is nothing even remotely related to sex or condoms you will see a Trojan condom ad. I brought it up a few months back on their forums and they basically said they didn't care and that there was nothing they could do about it even if they did. Actual quote from one of the Kong admins:
"I’m sorry – I admit, I chuckled when someone who’s last letters are “KY” was complaining about condom ads. But I digress…
As I posted in another thread, I don’t see anything wrong with condom ads (and especially bra ads) at this age group. People start to get sexually-active around age 13, and contraception is an important part of life. They should learn about this at home or school rather than through an ad, but I fail to see how a condom ad is harmful to a 13 year old. I realize that not everyone is going to have the same philosophy on this, but we’ve covered this in the past (I can link to the thread when I find it), and Kongregate does not have a problem with a non-explicit condom ad on the site."
And my username does not refer to KY jelly it refers to Ky as in Kentucky!
