Possibly not blogworthy, but: One puzzling side effect of running greytrapping (as chronicled in https://nxdomain.no/~peter/eighteen_years_of_greytrapping.html) is seeing the uptick in password guessing using even the obviously generated gibberish local parts, and the sheer volume of tries (see https://nxdomain.no/~peter/should_i_stop_caring_and_let_ip_reputation_sort_them_out.html and links therein). #greytrapping #passwordguessing #passwordgroping #spamd #ssh #pop3gropers
