Sam's club has some evil ads, first it does some sort of siren that wakes my phone up, and at the end of the ad it activates the mic on my tablet and tells me to say a phrase. I don't, but that's straight up badware.
Unfortunately, slacker got rid of it's forums a while back, and their support has never replied to technical problems I've reported in the past, so they'd likely not care about a malignant ad.
