Good job grabbing the screenshot.
For reporting these, here's what you need to send me via PM conversation:
1) A screeenshot of the ad on BYC
2) hover over the ad and right-click then "copy URL/link"
Send both of those items to me in a PM and we'll forward it to our ad partners. Having this info is important and gives them a better chance of tracking it down and blocking it.
I just sent you a PM but since I'm on my phone, I don't know how to get the URL without clicking on the ad.
