I'm fond of the ones with a fake close button, so tapping it just launches the ad's site. Instant uninstall and 1-star.
(Yes, I know it's mostly the ad's fault, but there's no practical way to punish them directly. So force apps to pick better-behaving networks.)
This is usually against ad network rules, so if you're willing to go out of your way a bit, you can screenshot those ads and report directly to the ad network
I'm not sure that is mostly the ad's fault. Hitting a target on a touchscreen is hard to do. This seems like it's the phone's fault first to me.
(If you're using a mouse, forget what I said. But I haven't run into an ad where the close button didn't close it... if you were able to click the close button.)
IME it's a real close button but the ad opens the thing when it closes, regardless of how it closes.
As a sometimes designer, i don’t think there’s any distinction between punishing the ad and the company. The company bought the ad, probably directed its creation, and decided what its criteria was for success. 1-star away as far as I’m concerned.
