I was reading some posts way back in 2000, and came across info on the ia_archiver from Alexa. (I have been spidered by them) The posts recommended blocking this spider because of the way it works.
How do I block a spider?
Thanks,

wbrook, welcome to WebmasterWorld.
You would use robots.txt to block the spider. The robots.txt tutorial [searchengineworld.com] gives complete instructions for this.
Here's another, specifically on access denial [searchengineworld.com].
