Right. You might find an online squabble going behind the scenes when information is added, deleted, and changed frequently. Moderators (!) will sometimes lock down a site when this starts happening.

There used to be a way to see who was behind some of the changes: SEE WHO'S EDITING WIKIPEDIA - DIEBOLD, THE CIA, A CAMPAIGN but evidently the site was taken down because it was expensive to run. Virgil Griffith was the author - perhaps he has other useful tips.
