Fullscreen ads on mobile?

[niclonnic]

First of all, I am an upgraded member. However, whenever I'm logged out of the site and tap on a forum using my phone, I get a fullscreen ad like the one pictured below. And yes, I'm able to just exit out of them. Does anybody else get ads like these on their phones?

If you're an upgraded member and logged in you wont get any ads on the site what so ever, however once you have logged out there will be no way for the system to know whether your an upgraded member or not, so to keep all ads off simply log-in.
