They aren't preferred targets so much as they are the cheapest targets.

These scam ads are trying to play the numbers game that email spammers do. So they just bid on everyone at the minimum bid. For people with fleshed out ad-profiles, the big advertisers that pay decent money will buy those slots. The auctions almost never fall through.

For people with no profile, no one bids, and the auction falls through to the scammer who will pay $0.00001 for their ad to load.

So ironically, the (second?) best way to remove scammy ads from google is to keep loading ads from google.

You're missing the fact that all ads are scammy and I don't want to see any of them. There's nothing that makes a Downy ad more honest or relevant to me than an ad for BigCoin Online Casino - it's all worthless trash that conveys zero genuine information about the product. At least the bottom tier ads are honest about what they are.

		That's totally fine, but then the correct action is to not visit sites that have ads then. The protest of the ad-economy is boycotting ad based services. Not using those services while blocking the ads. That just sends the signal that there is demand for free shit, which is both obvious and meaningless.

		There's nothing scammy about an ad for a Snickers bar. You can purchase it and it will be what they said it would be. As opposed to real scam ads where you try to purchase something and they steal all your money. Let's be truthful and honest. It's something to not like ads - I don't like ads - but you have no reason to muddle and distort a sensible conversation.
