I believe that Jesus existed because something must have happened over 2,000 years ago for us to start counting from that date.
Jesus also must have been pretty popular to get so many followers during and after his death.
If, in fact, you believe that Jesus preached love and forgiveness....if he made miracles happen, then he certainly was no 'fraud', but that's all a matter of faith.
If you have faith in a 'fraud', then they are not fraudulent - well, they are according to those who do not have faith, but since when do the opinions of the faithless influence those who have it?
At risk of yet another round of debating with my fellow Hindu brethren (which I am really not in the mood for), I see Jesus as another 'holy man' or 'sadhu' like Buddha or Vivekananda. He is the 'guru' for many, and his teachings are in the Bible.
If one believes in the Bible, there's no room to even consider that Jesus was fraudulent. He was just a divinely inspired soul. He may also have had certain social and political ideologies and influence.
I see Jesus as being a 'troublemaker' really...a threat to the status quo of the time. Whether that was deliberate or unintentional though, is unknown...but he died a martyr anyway - and 'religious martyrs' were pretty big in those days.
Even though I am a Hindu, I often get told I would make a good Christian minister. lol
