Ugh, rejections on penny hits are obnoxious. Partly my own fault though; I only glanced at the TO rating and since it was mostly green decided to try one. That'll teach me not to actually check the reviews. The most recent ones talk about tons of rejections. Sigh.
Requester is Dataminr, Inc., hits are Tweet Classification. Seems like they might be judged on majority rules (despite not mentioning it anywhere in the hit) as the feedback they left was that my answer didn't agree with others. But from others on TO it seems like they're rejecting for several reasons so who knows.
