"but there’s no real difference between advertising for a Ninja and throwing half your resumés away because you don’t like unlucky people" This assumes getting hired by you was a lucky event in their life. In fact, it could very well be unlucky. Perhaps if they hadn't been hired by you, they would have gotten a much better job elsewhere. Or any number of other things in their life might have turned out better had they not landed this particular job. Or maybe they'll wind up hating the job, and wish they'd have gone to work somewhere else. Considering someone to be lucky to work for you is very self-centered. Perhaps it is you who are the lucky one to have someone like them working for you, and they the unlucky one.
