The edits are done because they have to be they have nothing to do with ninja's lol nor are they secret.

If it was possible how do you think it could be done in a simple way.

How can you expect professionals to take VGC numbers seriously if they can undergo rapid changes without any trace left other than memory of forum posters?

It's all about credibility.

VGChartz numbers are cited in the Guinness Book of World Records, Forbes, the New York Times, and many other places.  And I've talked to some game marketing people and game reviewers who said they use our numbers all the time.

Any time numbers are posted they are estimates and subject to change.  You should expect small changes as data becomes more accurate anywhere you go, unless their numbers are psychic and their new data are lies.
