I can forgive and forget when ads are plastered all over the page and become a small nuisance. However, I can't do that for these ads. As soon as you load the page, a video ad plays and locks position on it, so you can't scroll down or up for the entire duration of the ad, which was one minute on my case. It gets even funnier when the ad plays again many seconds later and you have to stop typing. When ads prevent you from seeing the content of the page, you know it's invasive and it needs to be taken care of swiftly.
I have this problem on my phone, exactly as you describe it.
Hey! They got SONY on my amiibo! Wait a minute. Two great gaming tastes that game great together!
