We got this report this morning: "Something is up with HB on the iphone. It keeps redirecting to some gaming site and simultaneously opening my app store."

We've been researching the report all day, and it turns out that this is a new "malvertising" tactic that some ad companies are using. Somehow, our ad provider can't detect the problem (not sure why?) since this has been going on for a few years now. Here are a few recent article on what's going on... it's been affecting Reddit and imgur as well lately:

We are exploring technical solutions. In the meantime, we have blocked all ads related to "Mobile Phones & Accessories," which should block mobile gaming ads. It will be a hit to our revenue, but obviously we don't want anything to do with ads that work like this.

It may take a little time for the ad block to go into effect - in the meantime, please let us know if you run into a redirecting ad again! Thanks guys, and sorry about this...
