I suppose that it depends on how one defines the action of lying.
Yes, I have clicked ads that indicate one thing and are actually something else, or are obvious lies in my opinion. Some pass it off as "marketing". Kind of like misspelling a word in an advertisement to get attention. One that I like is:
"Do not stay behind and start your business through our platform."
I'm not sure if this is due to translation problems or intendional. It does seem to say the opposite of what I would think is desired. But is it a lie?
