Ad hijacking TCF on iOS mobile safari

I've got some weird iPhone and TCF behavior going on. I am on iOS 7 on an iPhone 5s using mobile Safari. When I visit TCF, I am being hijacked by an ad for an app that is then opening the App Store to the download page for the app. I am not clicking on anything. Sometimes it happens when I visit the main forum list. Sometimes when I click into a forum or even into a thread. The app is Jelly Splash.
