In my situation, "the other guy" ends up using MY first.last@g as HIS spam email; this has led to some embarrassing FWDs to his wife [from me], as he mistakenly provided their home phone number in to one of his spammers (so I got it, as he had used my email [instead of his] to keep spam out of his inbox). Too much fun, telling his wife about his porn-viewing habits and other miscellaneous secrets. I don't use email anymore, but I maintain this account just because it pisses him off... I think this high-up at some tech company (that shares my same name) secretly expects me to just hand over the account I signed up for fifteen years ago, now... not happening, Mr. S.
