Trying to reconnect my father with his old MSN buddies

(This was already posted in the AOE4 subreddit, thought I would try here)

I told him this would be a *complete* shot in the dark. My dad, who is now 57, bought AOE4. He *loved* AOE 1 & 2 (he hated 3 lol) and used to play online through the old MSN system. The first game I ever played was AOE and CIV 1 because of him (I'm 26). He went by Sirmauler on MSN and said the only friends he can remember went by the username "Ratboy" and another they called "Judge". He said it would be awesome if I could somehow track them down, but I made sure to preface him that it was incredibly unlikely.
