IPDetective collects data data from bot nets, datacenters, tor nodes, proxies and vpns. Is that what you are looking for?

Also IPDetective can be used just as a detection solution rather than a prevention solution.

Sometimes I use it against my nginx access logs and see how much of my traffic could be from bots.

I think your service would be close to what I'm looking for. But can you handle 120+ million requests per month? I would rather integrate an open-source list into our open-source tool than using a proprietary service.

I feel you. Maybe we could work something out.
