Never heard of them before now @reonlouw I believe you will have to stand in line with regard to the ad pop-up's.
I never used them since I personally don't like them, it is like an invasion of privacy. When you researching, reading and someone has those planned into the website design it has a red rag to a bull effect on me as well.
Good luck with the contest on @originalworks for trying not to use choice language, falling foul of what we all feel but dare not say.
Thank you @joanstewart. Glad I am not alone in this. Can't understand that it continues despite our irritation. I would think it to be a very unsuccessful strategy.
