You've seen plenty of those ads that start "_____ hate him! ______reveals the secret to _____" that are accompanied by a picture of the so-called expert you can buy information from. But sometimes the picture is of someone you recognize, like Isaac Asimov, or the gentleman here, who is Paul Karason. Karason was in the news a few years ago for having blue skin due to the ingestion of colloidal silver. Who selects the random pictures for these ads? I would not be surprised at all if it were a bot.
