Compromised E-Mail ID
I created a Hotmail e-mail ID specifically for registration on the new Chowhound site, and have used it for no other purpose. The ID does not appear in "my CHOW," nor is it something that should be easy to guess, nor have I used the same user name @ other domains.
I just checked the Hotmail Inbox for this ID and found a phishing message, as well as a rejection message indicating that a phisher had used my new ID to send spam to other users.
Has Chowhound/CHOW security perhaps been breached?
I've had that happen before with "predictable" names. For example, if I (or anybody else) have an ID called firstname.lastname@example.org, I would expect junk mail at email@example.com, firstname.lastname@example.org, and so forth.
This particular ID is sufficiently unusual and unique that I'm very surprised to see it immediately compromised. This has not happened to me before with similarly unusual and unique names--which is why I posed the question.
I think that's just a pitfall of using Hotmail. I've set up hotmail addresses and not used them for ANYTHING and gotten hundreds of spam mails within a few days of when it's set up. I have had it happen with Yahoo as well. I haven't had that happen with Gmail.
Try it with an address that you don't give it to anyone, and see what happens.
