Porter Stansberry & his newsletters are scams. Pure scams.
He puts out over 15 different newsletters under aliases any one time. He makes so many different calls that sure a few of then work out. If you somehow get your money back he then sells your info to anyone who will buy it. Then they wear you out on more crappy deals.
There are some decent newsletters out there if used the right way but why anyone would use Porter's newsletters is beyond me.
