By DoM: There is a zero tolerance for piracy. Zero, none.
Are you more concerned that the time you spent on your reply was lost or that the thread was closed? Perhaps the very idea that your reply was that important to you is an indicator that that thread was getting out of hand. But, yes, threads are closed in attempts to avoid issues. We would rather close a thread than to let it keep going and have to ban posters after it is all done with.
By GFC: @Stapel, if you had read the rules, you would've known piracy is intolerable here, and as for the thread that could've been described as trolling, well you've said it, it was trolling, so I'd just let dead dogs lie. Complaining about moderation has never helped
