Never ever confess your crimes online. Even on image boards, because it usually violates rule 1 and you can't trust the admin to not work with authorities. They are also arrows in the quivers of any enterprising doxer who wants to ruin your life for some reason (that is usually beyond your comprehension).
@nyanide I'm with @maxmustermann on this one. Why would you say that? Why would you post that anywhere? My rule concerning piracy is simple: I won't ask if you did it, I won't moralize about it. But DON'T be the moron who publicizes about doing it.
