It's bullshit, no doubt. A friend o' mine got fired for bad-mouthing a Mike South video. If the co. advertises in the mag, then you HAVE to give them a good review.
Which I would totally do, by the way, if the price was right. I mean it's only fuckin' porn. But the going rate, last I heard, was $25 a review. AND you have to give the tape/dvd back!
