Totally ungrateful 

I can't believe that someone would perpetrate intentional vandalism on a site like this which really espouses the ideals of information sharing, open information exchange, and honor-system based knowledge transfer.

I don't take his vandalism on my work personally, but I do take offense to two things:
1) People like this undermine the spirit of something like Wikipedia, something that has the potential to change the way that people learn and to help everyone in society have access to all kinds of information, for free (not counting Internet access).
2) People like this have no respect for the sacrifices of our predecessors.  Without people like Jimmy Launders fighting in conflicts such as WWII, and putting their lives on the line, the ability to openly share information and to have opinions would not exist - we would live in a fully censored society, as Nazi Germany was.  So by vandalizing Launders' page, this loser shows tremendous dis-respect for the risks that were taken and the sacrifices that were made by our ancestors who put their lives on the line and in many cases made the ultimate sacrific to ensure that we could live in a world where our thoughts, ideas, and communications were not censored.  But people like Kanupur don't consider that, they only think of things selfishly.

Personally, I'm glad that he's been blocked, and I don't care if he gets in trouble at work because of his work's proxy being blocked.  In fact, I hope that they do figure out that he was a vandal on Wikipedia, and that that's why his work's proxy has been blocked from Wikipedia, and that he gets disciplined appropriately by his employers.
