The bot blocker does do the Amazonaws but you need to find the correct useragent, so you'd need to block amazonaws.com, ia_archiver, alexa.com (unless you use Alexa for your web analysis), softlayer.com, scaleway.com and there are a few more, but the best way is to view your Who's Online page with useragent showing and copy the amazonaws strings in to the list in the mod then they are gone forever

As an added, use the tools I provide links to in the ban spider mod page and analyse the user agent string as it may turn out that that they have other associated and the one displaying is just a fa?ade.
