@gyptazy @solene spamd is a lot more targeted than that (SMTP only).
Any attempt to deliver mail to the trap addresses will lead to the sender IP getting stuttered at by my system and any similar system that imports my exported data on subsequent SMTP connection attempts for 24 hours.
If anybody out there uses the exported list of IP addresses for any other purpose, that is both stupid and entirely their responsibility.
SSH and POP3 gropers on the other hand are subject to "block drop" here.
