Thanks for sharing this. I'm asking publicly as I'm curious if this
message spawns any conversation, but have you seen or heard a lot of
intentional abuse around using bsdly.net email addresses specifically to
attack website owners? I find that emails to these bsdly.net addresses
seem to trigger immediate blacklistings at sorbs, which is still
relatively highly utilized. Effectively, this means that if I sign up
for a blog or mailing list, even if those websites do everything
correctly, and fill out an @bsdly.net address as if it were mine, the
confirmation email will cause IP blacklisting. A noteworthy blacklisting
at that, not just some insignificant RBL.
I, of course, mitigate against this now. The moment anyone on my
platform tries to email @bsdly.net, they're halted and flagged for human
review. But I don't consider that the most favorable position to take
because spam traps become useless concerning emails they don't receive.
I wouldn't mind the occasional blacklisting when it's deserved, even
though I catch them before anyone can even parse their logs, if the data
proved helpful at a larger scale. When a spammer breaks through,
consequences are inevitable after all.
So I suppose my question is, do you notice any significant amount of
behavior that could match my description? I would assume almost every
confirmation email you receive at those addresses (double opt-in to a
mailing list or website registration) would represent a case where
someone didn't purchase or scrape lousy mailing lists but instead was
targeted by a third party who wanted to cause them harm. Automated
social engineering at it's finest.
