Somethings got me bugged while looking at who's online. It seems that if you're not a member, you're a Guest, but if you're not a Guest or a member then you must be a Spider.. Yahoo! Slurp Spider?...Askjeeves Spider?..and judging by the names i'm thinking their also might be a Google Spider somewhere aswell lol. Although it's quite cool to be called a Spider, i never see them post (just watching us with their 16 eyes). Maybe i'm an *****, but what are they??? (besides Spiders).
That would be the bots used to crawl the web and index it properly, TechSpot had to be included of course http://en.wikipedia.org/wiki/Googlebot
Here you can even track the crawlers; http://www.softpedia.com/get/Programming/Other-Programming-Files/CrawlTrack.shtml So I suppose you could, (very loosely), call that a spider spider. I've seen a web crawler that hunts ISO files also, ostensibly to enable software houses to track illegal downloads. I should have bookmarked that, maybe somebody else knows what it is. A Goole search on "illegal download tracker" returns results such as these; http://www.google.com/search?client...d trackers&gs_rfai=&pbx=1&fp=7a5ff6e4754518c3
