I get the same three top answers, the only difference being in what place they are. On Google it was Github/Twitter/LinkedIn while on DDG it was Twitter/LinkedIn/Github. No problems here.
Did you find out how the guy looks immediately? I did not, and DDG even misinformed me. His Github, Twitter, and Linkedin are in the top5 results and all of them share the same profile picture, still DDG show some other picture for no good reason.
