I heard of one horror story on opiophile where this girl just finished her 2 year sentence. (she got off easy) LE set up a site on tor, it was totally ran by them and on another, they were just trusted members. And she said the exact same thing. IT totally blew her away when she found out they were LE. She really thought that they were her friends. They spent about 6 months of doing business, etc then one day, they lowered the boom. Got a lot of people. The big difference with what she was doing is that she was sending and receiving cash either to her door or through WU. So, she let her guard down. Had she not let it down, she probably wouldn't have gotten busted. Don't ever feel comfortable or safe with ANYONE!!! Keep your guard up.
