I had my doubts. The message is definitely not in anything resembling his usual voice. Has anyone spoken to him or confirmed that he is not in England or that he is OK?
Yeah it didn't sound like him, and two of the emails were copied and pasted.
Tom messaged me back on FB and said he gave him a call. He is not in England, he is a okay. 
Thanks for your concern, Swiss (and others!).
I was able to restore access to my primary Gmail account quickly, although not before many people I know had some interesting e-mail exchanges with this cretin. There does not appear to be anything compromised in my actual Gmail account and there is no trace of any e-mails to/from the cretin. He also took hold of a Hotmail account I haven't used in about five years and another rarely-used Gmail account.
I was, however, booted from Facebook as a result of this incident. (Considering the guy was scamming people using my account, I don't really blame them.) I'm attempting to have my account reactivated, but based on what I've read about Facebook's non-existent tech support that will probably take 6 years. I guess there is some kind of "appeals" process. I'll just send Mark Zuckerberg my Social Security Card, Passport, and a box of fuuuuuuuuuuudge.
What's particularly odd is that I was in fact traveling when this all went down on Thursday. It was domestic travel for a family wedding, and while the trip was harrowing in many ways, there was no Lebanese lambasting. Now that I think about it, that would have been preferable to the
hmotel my uncle inexplicably selected for just about everyone attending from out of town.
The only online activity I engaged in Thursday morning was a few failed attempts to use the free in-flight Wi-Fi via an iPhone. Is it possible this is the source of the hacking?
