@Jamie.R - I have a feeling that the same person asked me for some 'trades', this morning. My advice to you is to do what I did:
Reply to them, explaining that trading copyrighted material is not only unethical, but illegal, as well. Then, I reported the PM he / she sent me, to the mods, so that if the person continues, they can keep track of them.
I could go on a LONG discussion here, but ultimately, it happens here, so often, that I'd be filling up multiple threads, too often, and it's not worth the time or the effort.
So again, if I were you, I'd simply tell them no, and report it to the mods.
