We have been investigating this throughout the morning. This is coming from a programmatic advertiser, which means that it is not someone that advertises directly with BroadwayWorld. That is why you will see it on other sites as well. It is a scourge across the internet, specifically on mobile, and we work with our programmatic provider to block anything that behaves like this as soon as possible.
We just heard back from our provider, and they said that if it happens to you, if you send us the advertiser URL and the device and browser that you see it on, they can triangulate from there, and put it on our blacklist.
The best way to communicate that info would be to email contact[at]broadwayworld[dot]com. As that address is monitored nearly around the clock.
Thank you for your patience and assistance with this. It is incredibly frustrating to us as well.
