Just curious whether most bot blockers in the spider forum block all data centers just as a matter of policy or do you wait until something happens before quarantining an IP range?
I'm kind of 50/50 myself as I'll try to make sure I have all known ranges for places well known for bad traffic like AWS, The Planet, etc. but I don't look too hard for companies that run a pretty clean shop like Peer 1, RackSpace, etc. Therefore I'm proactive where I know there's trouble and more reactive in other places and address them only as they come along.
