Non-personalised ads might indeed be more scammy, but it should be the ad network’s responsibility to vet and monitor their advertisers. (Imagine Don Draper making ads for penis enlargement companies.)

Let’s also not pretend that personalised advertising is that great. Our Tizen runs the crappiest ads (can’t opt out in some cases). And I just have to take a look at my partner’s phone to see what personalised means, and which advertisers can _afford_ to get placement. (No, she doesn’t need another of the last 10 things we’ve purchased.)
