yeah. I agree. feds aren't gonna show up right away. they're like cats - they will assume that pounce pose and patiently wait.
can't remember the guys name, but he did the same thing years ago with script drugs. had someone to do the front end websites for him. looked good, worked great...delivered as promised, and then vanished. the site would simply disappear one day, but then another would pop up. and another and another. all very similar in look and feel. it was his attempt at dodging the feds - hit and run. don't stay around long enough for them to get their hooks in you was the thinking I guess. he eventually got popped and it made big time news. so I promise you, these guys don't stand a chance.
