Examining Wikipedia Anonymous Edits

It's recently been amusing to look at where Wikipedia's anonymous edits come from. There have been many self-serving edits from obvious places, as well as selfless ones from unexpected sources.

I am most amused by this selfless edit which came from IP address, which translates to webgw0.thls.bbc.co.uk.

I can only think that had the BBC person in question made an attributed edit instead of an anonymous edit, it would have been considered as coming from an authoritative source.
