In this paper, the authors explains about blocking the misbehaving users who access the blocked websites through anonymizing networks. In this network, many people misbehaving the popular websites like face book, orkut, hi5, twitter, etc... through hide the client's IP address. But, website administrator routinely rely on IP address blocking for disabling Access to misbehaving users, since web site administrators cannot blacklist individual malicious users IP addresses, they blacklist the entire anonymizing network. Such measures eliminate malicious activity through anonymizing networks at the cost of denying anonymous access to behaving users. But blocking IP address is not practical if the misbehavior routes through an anonymizing network. So, a new system is proposed to solve this problem using Nymble.
