Few would dispute the great usefulness of Google search. And most of us are willing to put up with the numerous ads that come along with the content. They are usually a small price to pay for the convenience and completeness of the information we seek. And we rarely have a choice of ads + free content vs. paid content. Sometimes the ads are distracting and/or invasive (especially ones with audio, video, or animation). But perhaps the worst ads are the ones that don’t look like ads at all. For example, the one in the graphic above, which is formatted to look just like the usable content itself. This strains the limits of ethics; at least in paper periodicals the advertisements are either clearly advertisements (as is easily seen by their formats) or are clearly labeled “ADVERTISEMENT”. Unless you truly need the content you found, we urge you to peruse other, more ethical, websites for your information needs. (It was interesting that we found this on a website dealing with CAPTCHA’s, which is another phenomenon of dubious merits.)
