I feel like I've told this story before on the list, but I can't recall.
It always feels worth telling.
When I worked at DigitalOcean I took what felt like a year (may have
been less) and I focused more energy than any one person probably ever
has at any cloud provider on tackling spammers based on abuse complaints
and recognition of patterns recognized from investigating abuse
complaints. I had Python scripts running through the customer database
at one point looking for key indicators and would mass shut down
accounts either before they started to spam, or not very long after. No
false positives. I would shut down a ton of accounts every day to zero
complaints, because they were all exactly what I knew they were and they
knew what they were doing. I had video meetings with several frequent
complainers who would come at us from social media angles to inform them
of how their complaints were informing my work, and what I was doing to
try to reduce their complaints.
Despite all of that, I don't think I ever succeeded in even reducing the
complaints. The only way to tackle this successfully at a cloud
provider, in my opinion, is to block SMTP traffic and only unblock it
under certain conditions. There will never be enough humans as dedicated
and capable as I was, without raising prices to the point that it drives
customers and spammers to the clouds that aren't spending that kind of
money on abuse handling, to make a difference.
Just my 2c.

Those two cloud providers are currently providing 99% of the incoming

googleusercontent.com sends a never-ending flood of DHL phishing mails.
linodeusercontent.com sends unsolicited ad crap using a domain

Time for large scale IP range blocking, I really can't stand this
anymore.
Is there anybody there who reads abuse reports, tracks down culprits
and *fooking shuts them down*?
Aggravated,
