Have you ever been tricked into being part of a "scientific conference" which was nothing but a website and a hoax? A colleague just notified me that my name was listed as keynote speaker for some conference and when I looked up the website, there was suspicious information, such as scope of topics (almost anything from A-Z), a conference fee waiver for next year's event in Dubai, publication opportunities for contributors and other goodies. Is this a common thing that I just had not seen yet?
