Recently I was looking for a computer technical solution on the net and as i was going through the google search list i got multiple Experts Exchange related results, and if you try to access them you get to a page that seems to have scrambled info asking you to register. (EE previously relied on cookies to bann you the secong time, but i think it was just an annusence not a prevension mechnisim.) I did find it old that google picked it up as a result... I kinda to a minute to scratch my head and then everything fell into place. they only bann you if you are a user.therefor what google sees is different to what you see, hence using the cachedversion of the site should yeild a result. but Where is The Data on the Cached Site!!! again they seemed to use an ingeanious plan to utilise the users ignoance and attention span. The data is there, but they restructured the site to look complete without the info where only after a few scroll pages the data is found. Cunning!!!! Therefor they identify you from google. as the solution cannot be an IP based identifier, a browser identification is the only solution. thus changing the is the only vaiable solution. I got stuck at this point. i got searching on the net to find an identical post to this on clazh.com , finally I got this from them "If you constantly land up on experts exchange or you are tired of scrolling down so much. Use the User Agent Switcher FireFox Extension to spoof your User Agent and make Experts Exchange believe that you are a Google Search Bot. Download a list of User Agents from here and import it using the user agent switcher extension." Hope it Helps Good Luck
