Like ubiByte says, most people are greedy bastards who would never share their hacks despite whining, crying, begging, and name-calling other people for not sharing hacks. Generous people like Nico, maddoggy00, and others are a dime a dozen. Even then, I wouldn't be surprise if they were holding some of their secrets back. The fact that coldreader even bother to post that he has hacks is probably more generous than most people can boast about.
