Yeah, I can sympathize that web sites need money, but if you're allowing ad services to serve scam ads then you've really lost your footing. If there's more ads than content by screen area, then you're not in the content business, you're merely an ad pusher.
And most ad networks are trying to show me the same ads on every site. They also use photos that have nothing to do with the allegedly advertised service, like they picked a random viral photo and stuck their ad under it. Then there's so many ads for various kinds of woo that won't solve the problem they claim to solve. Then there's the ad that "people from your nearby town(s) are scandalized by this one web site". "Don't eat this one food" showing a banana, which is false. Video ads on a site only offering static content is also wildly out of place.
