You guys all think that it's a good idea to post mislabeled stuff, but you all downloaded the file too. How would youj like it if you downloaded a file by "accident" as you say you have and you find some naked old man?
Mislabeled files are the last thing we need on Gnutella. That was one of the problems with Napster that made it suck so bad. Shame on you for your viglante censorship, you're as bad as they are.
I'm not an advocate of kiddy porn, but I also don't tell you how to run your life. Another above poster suggested that someone hack users who possess this file. Well, half of the posters on this thread possessed this file, whether by accident or not I don't know and I don't care. Should they be hacked too?
Just ignore the stuff you don't like and enjoy the stuff you do.
