Ah I see, thanks for clarifying everything!

Ah, I didn't know editing posts put them back at the top, although doesn't this mean people could be tempted to make tiny, pointless edits to keep their post high? (As opposed to making one large edit to make the post better)

I'd assume you got it on a post which was then deleted afterwards through moderation/flagging, but that's just me guessing, I'm in no way aware of the way the site is programmed.

As said by @Thomas Boxley the original poster should use common sense and not reveal that he uses pirated software if he does and wants an answer, as noone wants to be associated with an act of piracy.
