Murphy got the wrong Erik. I don't have the dox on the right Erik, but I have evidence that it is not Erik Kraft in Chicago.
Veromi.net and zabasearch.com show that Erik A. Kraft in Chicago is 33 years old. This is the same Erik Kraft suspected by Murphy, as proven by the registration on erikkraft.info, which is his domain on his résumé, the same one that is linked on Murphy's forum. One of the zabasearch.com entries for him shows that he once lived at the same address as the one listed in WHOIS for the erikkraft.info domain. That's Erik Kraft.
But the Erik that Murphy really wants once added his age and birthday
on a user page in 2006. He said his birthday is December 31 and he is 20 years old. That would mean his birthdate is 1985-12-31, turning 21 at the end of 2006. Today he would be 24 years old. Moreover, that same page says that he was born in Chicago, but there isn't any evidence I've seen that he lives in Chicago.
The User:Erik that Murphy wants is nine years younger than Erik A. Kraft in Chicago.
