I guess something needs to be done. Chances are, though, it's not the company doing the advertising... it's their affiliates.
I base this on the ads I used to see when I was searching online for guitar lessons. There's like a zillion "guitar course review sites," each one scammier than the next. All of them ranked one course higher than all the others, mostly because it paid the biggest commissions.
The thing is... it's an excellent instruction course -- it's well-produced, with quality lessons that don't even claim a new "magic" method. It may not work for everybody, but the cost is fair value for the product received. I'd be comfortable inviting any of friends interested in guitar over to my place to take a good look, try a few a lessons, and decide if they wanted to by it. (That is... it doesn't embarass me that I paid quite a bit for it.)
What I'm getting at here is that ECF would have to very careful about information is presented in a sticky. If an affiliate, unknown to the company, was making stuff up, pointing the finger at the company itself could be troublesome.
On the other hand, the company that produced the guitar course didn't seem very interested in policing the tactics its affiliates used, which does take them down a considerable notch in my book.
