You need to e-mail Rick Vanner and send him your suspicions and proof or whatever.You can also e-mail a mod.This kind of thing gets out of control quickly and it's not going to be a witch hunt.
There's a right way and a wrong way to handle this stuff and this is the wrong way.
If there is an issue with piracy then it needs to be dealt with by the rules and those who enforce them not by a forum lynching.
And posting the peoples' names is unprofessional.If they violated the AUP they will be moderated like everyone else but if are mistaken you have just damaged their forum reputation by doing this.
And,as has been pointed out earlier,there is a sticky about piracy.Please feel free to check it out when you get the chance.
Just think...how would you like to sign in to the forums and find out you at the top of someone's pirate list?
I think piracy should not be tolerated and it should be punished.
But we have proper procedures for taking care of these things and they need to be followed.
Please have mercy and use the search function.
