AWS and Rackspace are terribly expensive, GoDaddy is huge in the domain space but not particularly big in hosting, besides shared-.

Why not look at the likes of OVH, Hetzner, Voxility, Colocrossing and so on. Or maybe try Level3, their business may be a bit different but they're HUGE and certainly forward abuse reports.

I'm no expert, but a quick Google leads me to http://www.webqom.com/blog/2016_web_hosting_market_share_tre..., which states that GoDaddy is the most popular hosting provider out there.

Yes, Godaddy sells lots of shared hosting at insane margins.

These insane margins help pay for a big abuse department.

Most dedicated hosting providers don't have as big margins because they can't stuff 1000+ customers on one server.

Most dedicated hosting providers don't have very big abuse departments, or any abuse department at all.
