It actually triggers anger in me when I've started to read and something pops up over it. It's the least likely way to get me to click your thing.
Whether you succeed or not is immaterial: the ad got clicked on, and hey, even if 99.9% of those clicks are accidental ones that will never convert, they still look like "organic" clicks and the ad revenue still gets booked. Expensive consultants like this person ( https://news.ycombinator.com/item?id=12944902 ) will chalk it up in the "users engaged" column. Everybody gets what they came for... except you and me.
