I run a personal web server from my home. I have found Digital Ocean IP addresses as a frequent source of stupid web server hack attempts (e.g. trying to hack wordpress - I don't run wordpress). I sent complaints to their abuse department to no effect, so I now block all the Digital Ocean netblocks that show up in my logs.

My conclusion is that Digital Ocean doesn't care if their tenants run hacks and scams.

FWIW, I rarely get scans from AWS. When I do, I report it - I get a response email logging the complaint and a day or two later I get a follow-up email closing the ticket and saying "it's been taken care of."
