LiveReviews.com tests all sites using a unique Visa credit card number, this is the only definite way to see what a real customer would get should they join the site.
Other review sites ask the site owners for a username and password, the problem with that is as follows:
1. The usernames and passwords site owners give out to review sites, may or may not be rigged in a way whereas it shows the members area with way more content and non DRM encoded movies. We use a real credit card to join, what we see is what you get.
2. By using a real unique credit card for every site we join, we can report back to you if we saw additional suspicious / fraudulent charges.
3. By joining as if we are a real customer, we can report back as to how much spam we got after we joined the site.
4. Other review sites allow users to post comments, rest assured many of good comments are from the website owners themselves and many of the bad comments are from competitors. LiveReviews buys real memberships and records it for all to see, allowing you to see exactly the truth and nothing but the truth
