[Update: he tried again, and when I asked if the scam actually worked on anyone, he responded with a butthurt message insisting he was a real person offering honest assistance, and calling this post “cyber-bullying”. Best laugh I’ve had all week.]
Obviously machine-generated spam based on scraping search engines, since the suggested replacement has absolutely nothing to do with the original link. Never mind the fact that it was sent from a site hosted in Amazon’s cloud (rickgrimes.asoshared.com, which identified itself as www.buzzstream.com to the next hop), or that it was sent with JavaMail and includes a List-Unsubscribe header. Those just ice the spam-cake.
To: jgreely+temp201501@dotclue.org Subject: Found an error to fix on your website Date: Wed, 28 Jan 2015 14:55:14 -0800 (PST) Good Afternoon, I'm a criminal justice student and I recently visited your site while researching for a paper I'm working on... This is a note for your webmaster, as I found a dead resource link on your site that visitors like me might be trying to access. It's on this page: dotclue.org/archives/001527.html I got an error message when I tried to click on the link to this site: atf.treas.gov It looks like that website no longer exists... anyhow, I found another link that might be useful in its place so your visitors can still find some helpful information: http://www.safewise.com/resources/guns-at-home Thanks for your help and for providing great information!
