As much as I hate to feed into anyone's paranoia about posting here, I also got the same email this morning to my JWD email address.
I've had this email for a little over a year and it gets twenty times as much spam as my other email addresses, which I've had for probably four years or so.
Then again, spammers and email address brokers scan many many discussion boards for legitimate email addresses, so it's not necessarily a disgruntled JW out to rain Jehovah's Righteous Spam upon the frenzied apostates of JWD.
Hmmm
