Please read- need help with a moral decision

[AztecWarrior]

I've already talked this over with my mom, and I wll do so with my dad once he gets back from Chicago.

I have to be vague. I am sorry, but I can't reveal any names or places. I think there is someone in the related party on this forum.

IF YOU KNOW WHO I AM TALKING ABOUT, KEEP YOUR MOUTH SHUT!

I can't tell you how it started. But basically, a certain group is involved in warez. I have decided that this is morally wrong (Thou Shalt Not Steal.) You can't convince me to change my mind, and that's not the moral question here.

Two of my real-life aquaintance/gamer buddy (not real friend), whom we shall call "X" and "Y", are among them. X and Y do not know I am there, I am posting under a pseudonym (I am not posting as AztecWarrior.)

I have reached the conclusion (and you may beg to differ here) that what this group is doing is equivalent to breaking and entering with theft. Just because two of my friends happen to be in the group does not mean you shouldn't call the police.

I am considering reporting them.

Most likely, they will get a cease and desist. However, if they need my name, or go to trial, I will be screwed as I will be called to the stand...and then the secret's over.

I want to do this if I can be assured that:
A: I remain 100% anonymous.
B: There will be no huge consequences, such as fines, jail time, or being sent to trial.

I do have a firewall, which supports my identity. (however, it does mention my ISP, which is inconsistent with my pseudonym.) I can try using a CGI proxy.

As for the reprecussions, I am not sure.

A major problem is that this is partially fueled by revenge. X and Y have not been the most loyal and caring friends. Granted, not a huge part, but a little bit.

So what do you think? Should I go ahead, or think about it.
