Hrm.. you know, there could be something here. If people kept posting variations of NP problems as jobs on sites like GetACoder as a honeypot, you could easily devise a blacklist from all the bids as people you'd never want to hire for a real project.
That's actually kind of brilliant. I'm looking at this reply that reads "Hello, Easy job for me,please send me a PM ." and thinking, "you stay away from me." This one is also golden, "Read your requirement and everything has been understood. We have already delivered a couple of similar projects and given our strong capabilities. I am confident we can deliver a powerful end-result to you as well."
