If these guys are serious about their business they are using proxies to obfuscate who they are. There are many services now that are claiming to have a ton of IP addresses Luminati, Shadio.io and Nohodo are just a few examples.

If these guys are serious about their business, then they should behave like a good netizen and obey robots.txt directives.
