    i was quite surprised to discover that no one had registered deleteduser [dot] com, and was curious to see how many emails i'd get if i registered it, assuming many orgs 'delete' logic probably just overwrote the email address with blahblah@deleteduser.com or similar.

    The answer, is at least 3 different orgs in the hour that I've owned that domain and been listening for email.

    And yes, all of those emails contain the actual PII of the person who has been 'deleted' 😄

      @SecureOwl reminds me of donotreply.com and other domains not to be used for that!

      @kkarhan @SecureOwl I had to dig up this 2008 WaPo story from Archive since WaPo nuked all my blog posts from their site. It's about @chetfaliszek, the guy who registered donotreply.com.

        it seems like some orgs do this with active directory users too for some reason.

        lots of things like internal alerts/monitoring

          could probably achieve something similar with notarealemail.com

            @briankrebs @SecureOwl @chetfaliszek oh yesh, I remember that one.

            Needless to say I think #DoNotReply-Addresses should be outlawed and using one should get a domain banned until the operators apologize personally…

              @SecureOwl

              MS used to tell folks just use .corp, which is why there still aren't gTLDs for .home, .corp, etc. too many collisions with illegal but heavily used (and leaked) internal names with those TLDs...

              lots of bad advice that lingers long after we figure out just how bad the advice is...

                @paul_ipv6 @SecureOwl my favorite was a customer of mine who had an AS400 and set up their LAN *just* like the IBM documentation, including using some random public IBM subnet that was used for the examples, lol. 192.0.2.0/24 is a very useful thing indeed.

                  that problem with folks doing that from examples in ipv6 is a large part of why we have reserved IP ranges for documentation.

                    @SecureOwl I have a semi-plausible reason to own multiple domains similar to consumer ISP mail services. I get some funky stuff courtesy of people who can’t get their email right when they tell someone their address.

                        @SecureOwl when I see posts like this I'm never sure how I feel.
                        One one hand, I'll never be short of jobs. Yay!

                        On the other hand. *Insert many expletives here* how the *expletive* do these *expletive* idiots think that that isn't the most *expletive* stupid idea on the *expletive* planet do do something so *expletively* *expletive*. And then I cry because I'm one of the people that has to fix the mess they made.

                              I remember when an 79 year old pastor from Illinois signed up for Twitter with username CONNECT

                              (after six months of back and forth "technical" correspondence with him, he finally started figuring out what a service keyword was ... since about every hour of the day he got some new, goofy system message)

                              * by the third year, the patient ol' guy changed his username to CONNECT1492 bless his heart, RIP)

                                      i was quite surprised to discover that no one had registered deleteduser [dot] com, and was curious to see how many emails i'd get if i registered it, assuming many orgs 'delete' logic probably just overwrote the email address with blahblah@deleteduser.com or similar.

                                      The answer, is at least 3 different orgs in the hour that I've owned that domain and been listening for email.

                                      And yes, all of those emails contain the actual PII of the person who has been 'deleted' 😄

                                      @SecureOwl Considering they can't just use null, what could be an acceptable option? @invalid? Although, to be fair, if they can't just null is because something is validating email, so it might require a TLD. Nah... I guess there is no way to rationalize this.
