This is an interesting one. Video Professor Inc is filing a federal claim in court against 100 anonymous John and Jane Doe's alleging commercial disparagement, false advertising, misrepresentation, and posting false and defamatory messages on infomercialscams.com.

Video Professor sells computer training videos and according to many disgruntled users, the company misrepresents itself and then confuses unsuspecting candidates into buying subscriptions they don't actually need or want. And although there is a 100% money back guarantee, attempts for refunds are futile. According to one user:

"I had purchased one piece of software from Video Professor... before I knew what was happening, my credit card was overdrawn and more attempted charges were constantly occurring. I kept calling customer service, returned the original software and heard many promises of the 100 percent refund, less S/H. This has been over 3 years now."

It gets better. Video Professor Inc contacted infomercialscams.com under the premise that they wanted the identities of all the people who had posted the comments, so that they could address their issues one by one. Two months later, Video Professor Inc has instead decided that suing them is the better option.
