If you really want to know what the motive is - look at how passionately the OP asks the question and how easily he goes silent afterward. Initial impressions haven't changed on my part - I mean, this is the easiest approach to building traffic to a promoted website. If more and more new users do the same thing, I think it will cause a disturbance. I'll ignore such users from now on and whoever you are, be wise not to fall for their strategy.
