The update you have been waiting for:
"Eighteen Years of Greytrapping - Is the Weirdness Finally Paying Off?" nxdomain.no/~peter/eight... (tracked bsdly.blogspot.com/2025/08/eigh...)
now has the complete 2025 data. #openbsd #spamd #greytrapping #spam #antispam #cybercrime #spamtraps #blocklists
Possibly not blogworthy, but: One puzzling side effect of running greytrapping (as in nxdomain.no/~peter/eight...) is seeing password guessers using obviously generated gibberish local parts (see nxdomain.no/~peter/shoul...). #greytrapping #passwordguessing #passwordgroping #spamd #ssh #pop3gropers

And yes of course, that became a fresh spamtrap, number 8205067 or thereabouts. see the old favorite nxdomain.no/~peter/eighteen_years_of... #greytrapping #openbsd #spamd #cybercrime
