There was a discussion about a type of ad that is annoying some people, but I’ve been away and can’t find it. The scheme is this: random words in an article will be hotlinked. A casual reader may click on the link to get more information, only to find out it’s an ad that has nothing to do with the article. I think that an ad pops up on mouseover.
A friend wants to try it out. What are the details, and where do you get it?
