Well, I personally don't really find the ads gross in any way. I'm a guy. But I don't find them attractive either, they're just one of those "yeah whatever" things. There's actually worse stuff on television, even on the single digit channels (at least here in America). Since I never pay attention to ads, their frequency doesn't really annoy me. The only ads that annoy me are the ones that make noise.
But they are everywhere, they're evn in Hotmail. And it isn't the only online game that has innapropriate ads, there's a whole crapload of them. It's gotten to a point where a friend of mine won't let his kids go on the internet at all.
Swordfight! My cheesy little first game!
