It has been almost impossible for me to browse this site on my iPhone in the past couple months. Some ad in rotation does a redirect to this pop up page claiming "click here cause you won 1000 dollar gift card" for a seemingly random selection of Google, Amazon, Walmart, Verizon, ATT, Android, Samsung, etc.
The page locks out controls of the browser somehow, you cannot load new pages through the address bar (type them in, but what ever the page is doing it never actually allows you to change pages. And floods your current browsing history with duplicates of itself so you can't use the backward button to go back to the page you were on.
Only solution is to close the browser page that is currently loaded.

I'm unable to actually find the ad that is causing it because the page loads, and sometimes redirects right away, other times I can be reading the page for a minute or two and then it redirects (I'm assuming at that time the ad is cycling?).
I thought maybe it was my phone, since this is such a frequent and obvious problem that others must be seeing it. But it's only Allakhazam's forums that do it to me.
