AD or virus

Could be a virus, never seen a site takeover banner here.

On mobile, I often get really aggressive ads here that redirect to another site. I just close the tab and load my bookmark again. It will usually go twice in a row, then not happen for a few days. The current one I've been seeing looks like a wheel-of-fortune spinning wheel game, but I never read too closely.

EDIT: Just got one that tried to redirect to app store.

Probably malwear.

I've been getting then the last couple days. I've been able to go to my browser's history and pull up a previous iteration of the q&a page. It's annoying as heck though.
