Tor is a form of Anonymzing networks comprised of virtual tunnels that allows people and groups to improve their privacy and security on the internet. Individuals use Tor to keep websites from tracking them. Anonymzing networks provide users with anonymous browsing capabilities over the web using a series of routers to hide the client's IP address. Under the cover of anonymity, certain users have repeatedly launched deface/DoS attacks over popular web sites such as Wikipedia. Since web site administrators cannot blacklist individual adversaries' IP addresses, they end up blacklisting the entire Anonymzing network resulting in loss of service to genuine users thus effecting entire Anonymzing network services.
