As an anecdotal aside, approx. 70% of incoming portscanners/rdp bots/ssh bots/etc that hit the firewalls at my sites

I used to send abuse emails but eventually gave up after receiving nothing beyond "well, aws ip's are dynamic/shared 
so we can't help you"

Last week we found out that Helpscout sends email from AWS servers.

Thank you, Helpscout, for forcing me to lift the AWS blocks on my incoming MTAs, that were cutting down my incoming 
spam scanning load by a factor of two.  At least.

Note that I work for an email hosting company, which makes this infinitely more annoying.  A factor of two, in this 
case, is a non-trivial number.
