common, Spain?
this guy's a scammer. what idiot sends you hundreds extra on a check? i've gotten a dozen emails like this. just ignore him, or add him to your blocked address, or bin as SPAM.
this guy's not going to the authorities. better yet, tell him to go ahead and contact the authorities, and that you've sent also sent a note to FBI. tell him you used it already to wipe your behind cause you ran out of toilet paper.
