There is no valid reason that someone should hit my site from an amazon AWS box. I'd love to just block the whole of amazon AWS/etc straight at the firewall. But I'm worried that I'll somehow block an amazon crawler/spider and that would possibly impact the sales I do on amazon.
Anyone have any suggestions/links for this sort of thing? I want to allow, if it exists, the actual amazon company to browse the site but block amazon's AWS/etc customers who spin up a server then scrape/spam with it.
