This was not a hacking contest. The specific request was:

"I'll give $100 USD to anyone who can trick me into inserting the string "BackdoorPoCTwitter" into a release of any of my software projects."

Emphasis on the "trick me".

As far as I could see, it was a request for social engineering (or some other oversight error). It's an interesting way to see how easily someone can make you into "the human element" in an attack.
