HN users have established a certain amount of trust in each other that lets us evaluate links in user's comments differently than links in other places, especially if the comment is upvoted. Your "technique" shows exactly that. If you would write anything like that on a thread NOT about advertising, you would just be downvoted and not get almost any clicks, so I don't agree that the same techniques work on everybody. Screening technique exists exactly for that - to screen people on who the techniques won't work.
