Just to show how easy it is to figure out your browsing interests, go ahead and disable adblock and see if what kind of advertisements you are pushed. Where do you think the advertisers figure out that what target group you fit in? Anyhow, email phishing in most cases is like fishing with shotgun, shoot in the general direction of the fish and wait for results.
