palmerj3 writes in to give some wider attention to a piece on Techcrunch today in which Michael Arrington reacts to Video Professor's desperate attempts to shut him up after he called Video Professor a scam in a piece syndicated by the Washington Post. As described by Arrington, the ways the company's site operates (differently depending on where a visitor comes from) are strongly reminiscent of the practices a Senate committee recently condemned. (Here is a detailed example of another, similar scam, from a not-naive victim. Video Professor's tactics sound even more deceptive.) Video Professor seems to react with belligerence, not to mention legal threats, towards any hint of criticism. Please share any direct experiences you have with this outfit.
