Nasty looking mobile ads Answered
A buddy of mine showed me this pop-up ad he got when he was looking over a guide I made recently. He had the same issue the last time I made a guide. These pop-ups are annoying enough that he never uses Instructables because of it. To be honest, I don't blame him.
I know you guys use AdSense for advertising and I don't really know the solution to this issue, but I wanted you all to be aware of it. Less internet savvy people might be freaked out by ads like this.
