Of course. But this isn’t spam we’re talking about; we’re talking about what appears to be a single individual flying off the handle at something posted on a personal website. I’m happy to admit that it may be a joe job, though Occam’s razor implies it’s just a luser who happens to work for the Navy and thinks it’s OK to send abuse with their computers. If I report this matter to the appropriate Navy sysadmin, it will be trivial for her to confirm whether or not the abuse is coming from their servers. If they determine it’s not, then it will be appropriate to start looking elsewhere. But at this point there’s no reason to assume that the individual has the inclination or expertise to spoof his headers.
Ordinarily I just ignore stuff like this—I occasionally get messages like this which I assume are from immature teenagers or neanderthals—but seeing as these messages appear to come from the US Navy I was a bit concerned. I don’t like the idea of immature teenagers or neanderthals having control of DoD resources and figure that the DoD doesn’t either.
Oh, I agree. I certainly wasn’t trying to talk you out of reporting it. I was just sayin’.
Can’t dudes dial toll free from England? 
And yeah, I read that, but I wanted more details, like what the Op said in his website.
Just some tongue-in-cheek humor, and nothing objectionable. In fact, if it’s the piece I think it is, it’s just some stats-geek humor on why he’ll never get a date. Either that, or it’s a bit detailing some moderately ‘Dilbert’ behavior on the part of an acquaintance.
Either way, it’s nothing any reasonable person would find objectionable at all.
Yes, but only within the UK.
His messages claimed to be in response to Why I Will Never Have A Girlfriend, a mathematical humour piece which was published in The Annals of Improbable Research.
Whoah!
You’re published in AIR? Wow - that’s a real claim to dubious fame!
Great article, thanks! 
I have never been published anywhere cool like that. 
That selfsame thought crossed my mind.
What on earth did he find so objectionable about that piece?
I know, right? Maybe he’s Bhutanese (Bhutannic? Bhutanish?) and “babe” is an insult? Perhaps he took issue with the mathmatics? Perhaps he’s just insane.
Seriously, there is nothing wrong with that piece.
