I actually have to disagree with a lot of the people here. Most big sites are infact nulled and not legit. The reason for this is because their legit vB and IPB licences have being suspended. Their's nothing wrong using nulled if you know what your at. It's dump ass people who forget to delete the validated.php file and other stuff that gives them a bad name or they use a shitty nulled source like MOBiLE.
