Not on an ongoing basis, but I was curious as well, so a quick mailbox 
search for 2015:
subject: Facebook outage?
author: Colin Johnston <colinj at>
subject: AOL Postmaster
author: Colin Johnston <colinj at>
subject: Getting hit hard by CHINANET
author: Colin Johnston <colinj at>
subject: BGP offloading (fixing legacy router BGP scalability issues)
author: Colin Johnston <colinj at>
subject: 20-30Gbps UDP 1720 traffic appearing to originate from CN in last 
24 hours
author: Colin Johnston <colinj at>
subject: de-peering for security sake
author: Colin Johnston <colinj at>

I tried to be pretty wide in the search and filter through a decent chunk 
of false positives manually, though of course I could have missed some.  It 
does skip a few of the "all of their traffic is crap and abuse reports are 
ignored" messages that don't *explicitly* call for wholesale country-level 
blocks or de-peering.

I was curious, but not masochistic ;)
