What Hacker News says?
The probable reason is that somebody did not like my reporting on the fairly obvious "sextortion" scams, in this piece https://bsdly.blogspot.com/2020/02/the-sextortion-scams-numb... which is also available as https://nxdomain.no/~peter/the_numbers_show_we_have_a_failur... . Enjoy! And I still refuse to believe anybody would actually be sexually aroused by any of my published writing.

HN discussionYes, some idiot keeps adding the "porn" tag to the site for some reason. Anyway, the article in question is also available, trackerless and with "classic" formatting at https://nxdomain.no/~peter/better_off_with_pf.html - normally my WIP to show early reviewers spot.

HN discussionThe big news for some of us is that Exim has been dropped from ports. Here is a good article about transitioning from Exim to OpenSMTPD: https://nxdomain.no/~peter/time_for_opensmtpd.html I tried using OpenSMTPD a long time ago, shortly after it came out, but things were not stable enough. I guess it is time to give it another go...

HN discussionThe redacted screenshot at https://nxdomain.no/~peter/blogpix/likely_suspicious.jpg indicates that the sending server used an IPv6 address that ends with the digits 19. The SPF record for bsdly.net includes two IPv6 addresses, neither of them ends with 19. It also includes some more things, up to three layers of indirection so I'm not sure I checked everything, but I didn't see …19 anywhere. I suspect that what we h…

HN discussionThe "Sextortion" spam is in technical terms mind-numbingly boring, following the same patterns as other spam to a fault, distinguishing itself only in the embarrasment approach to extortion. Interestingly, this piece seems to be bot-labeled as "porn" for some DNS based blocklists, so the author has made the text available here too: https://nxdomain.no/~peter/the_numbers_show_we_have_a_failur...
