Whats this all about? Quite intrigued to know if this really is true and how it all works.
I find it hard to believe (I did read it in the Sun after all) that there is some secret 2nd web where all these wrong doings go on from guns to drugs that you can mail order????
There are a number of sites that are never crawled over by web spiders, there are no refusers to them and they are shut off from prying eyes using varies security methods.
In short, unless you have the key and know exactly which door your looking for you will probably not find it.
This is commonly refured to as the dark web, its not indexed.
If you Google The Hidden Wiki you will find out a lot more of what you want to know. Its not some magical place of crime and drugs etc and its very easy to access.
