Also in deference to those who don't like long posts:
*This is dishonest, like the sponsored "science" where unfavorable results are buried in a bottom drawer somewhere.
*Honesty (as opposed to marketing) demands that we publish all reviews.
*It's probably good marketing. Yes, marketing involves telling less than the truth.
*If there's a negative review and that person knows ANY of our other clients, we'd better be ready to solve their problems. Are we that ready? With ALL customers? Including the guy who didn't want me to have the particulars of his internet account, but called me last Saturday night at 11:30 about an outage?

I think the disappearance of negative reviews that this seems to foster will just contribute to suspicions about what we do.

And what about the person who really wants to complain and tries to do so by giving a 5 out of 5 rating, making the system think it's a positive review, then proceeds to write how bad things were?
