If you see the thread has been deleted, why question it publicly? It probably is even more annoying for them to now have to delete this one too and making an issue out of it. As said you should just address it privately and move on.
I deleted your thread...If you or your friend wish to partake in illegal activities leading to an arrest this board is not the place to come to for advise on how to deal with that...Those are things you should have thought about prior to getting involved with anything illegal to begin with.....
