Just as the title says: Have you ever clicked on an ad, knowing it was an ad, on purpose? What ad was it? Why did you click it?
Curious because I realized I have not once in my life clicked on an ad shown online on purpose. Accidentally, and being tricked into clicking the wrong thing sure; never with intent though.
Twice that I can think of.
Mealbars while on Slate Star Codex, and when I was a young weeb I clicked on a web store that sold Japanese items to Americans.
