I received a message today from robot@craigslist.org that tripped my scam alert. If you look at the message, and the fact that it's coming from what looks to be a authentic email address, it would be easy to be fooled by this one, because Craigslist does in fact use a robot to confirm listings. However, that robot usually sends a message right after you post your listing, not a week afterwards. And this looks similar to that message, but something seemed to be off. What reallly got me to doubt it wasn't the multiple exclamation marks, but the use of the word "ADD" for advertisement.
So I looked at the email message header, and found the scam in the reply-to line:
Reply-To: "craigslist - automated message, reply for verification" robot@crajgsljsts.org
How does the scam work? I did my due diligence and came up with the following scenario from someone who feel for this:
You respond to the message with your post information. This allows the scammer to replace your post with their for sale post, which now looks like it is coming from you instead of them, thus giving it a legitimacy they wouldn't have had, and possibly also making it look like the advert is local.
The original message is reposted below so others who do a search may find this based on the text in the scam and not fall for it.
