I cracked it ... wait ... no ... that's not true ... I forgot ... never mind ...
It's still a douchebag thing to do. It's like winning a million dollars without telling anyone how you did it and adding to the insult by not sharing it. Oh, and if he's sharing the cracked program with his friends, then that's being a bloody hypocritical wanker.
Personally, if I won a million bucks I wouldn't go publishing it on the internet. I don't really like the ideas of a whole bunch of people showing up at my door looking for money. I'm sure the same goes with him. He doesn't want a flood of PM's asking for a link. Unless you're one of the people he personally informed of this (not me) and you personally feel he has a good reputation or he gave you pics, links, etc, you can't even be sure it really happened (this is the internet after all).
