It's 2014, and I'm browsing a review website owned by the internet giant Amazon.
There's no option to report the ad. I assume the close button is supposed to mean "I'm not interested in this ad, please show me different ones instead." (I wouldn't recommend you click anywhere on such an ad, by the way). AdChoices, the button next to Close... technically gives you an option to report this ad, but basically only if you're a lawyer. (You need to either own a trademark being misused - as Windows is here - or read the T&Cs for Google's ad service and find a violation.
I chose "ad takes over the screen" from the close button menu instead, which allegedly flagged the ad for human review. However I saw an identical ad minutes later (on the same site), so the close button doesn't seem to do anything.
Nor will I feel guilty about providing AdBlock on people's computers to protect them from fraudulent adverts like this one.
If I use your site regularly I'll start to trust it, and if I don't remember seeing abusive ads on it, I'll make a good-faith effort to unblock you. Personally I will not tolerate attention-grabbing animations, but I can't speak for others and I have cognitive differences.
