[tor-relays] Collaborative Bad-Abuse-Sender Blocklist

[Matt Corallo]

Hi all,

I run a few relatively-small exit nodes, and still get a decent flow of the usual Fail2Ban, blocklist.de, and such 
garbage to abuse PoCs. I tend to proactively find appropriate abuse/noc contacts to provide a response informing them of 
how they can appropriately block all Tor exits from their SSH ports if they wish, but often get either no or indignant 
responses about how sending a stream of garbage abuse reports is a useful service to the internet (nevermind that most 
large providers don't bother handling abuse reports anymore because of exactly this behavior). After a reply or two I 
usually add senders to a blocklist and bounce them at the mailserver with a notice about spam not being useful.

Is there any interest in building up a shared blocklist of senders who feel its their right to send Fail2Ban emails in 
non-machine-parsable formats and not bother handling replies to their emails they expect others to handle, or does 
anyone already have such a list?

Matt
