Some bots will do this to make it seem like they are real so their account will be approved for posting. You can ignore the buddy request and private message. If the user does not respond, feel free to ban him as he's probably sending buddy requests to others as well.

UPDATE:
I modified his account so he will receive private messages. I will also send him a message to see if he is a legimate user. His email address seems legitimate at least.
