I'm still new to the details of the unfolding scandals surrounding Wikipedia, so I don't know how to find or to use this Wikiscanner tool. Someone who does know how to use it should track the edits on Wikipedia's "hydrogen vehicle" article. It has all the earmarks of being edited, at least in part, by the p.r. department of General Motors. It would be par for the course at Wikipedia.

This is all I could get WikiScanner to do, it wouldn't go further. "Too many connections"

I don't know how to interpret what you posted.

A few things to not here.

At present, it would be very difficult to use wiki scanner to get this sort of information (remembering, for a start, that it has only anonymous edits stored).

However, due to a quirk when founding the internet General Motors controls 0.417% of *all* internet addresses: specifically 12.x.x.x, as well as some other ones. So looking at http://en.wikipedia.org/w/index.php?title=...&action=history you can quickly find sophisiticated editing by the GM PR dept such as:

http://en.wikipedia.org/w/index.php?title=...oldid=118193342

The above was done from memory and is complete bollocks.

http://wikiscanner.virgil.gr/f.php?ip1=198...198.208.6.0-255

You can then choose an IP range or two from that list and view their edits. I couldn't select them all.
