Traffic laundering is the process of routing internet traffic through a series of intermediary servers in order to disguise its origins. This can be done for a variety of reasons, including to evade detection by law enforcement or to avoid being blocked by filters. There are a number of ways to traffic launder, but the most common is to use a network of proxies. This involves setting up a number of servers around the world that act as intermediary steps between the user and the final destination. The user's traffic is first routed through one of the proxies, which then forwards it to another proxy, and so on until it reaches the final destination. The use of proxies makes it very difficult to trace the original source of the traffic, as each proxy only knows the IP address of the server that it is forwarding the traffic to. Traffic laundering can also make it difficult to block specific types of traffic, as the traffic can be routed through a number of different proxies, making it hard to identify and block all of the proxies that are being used.
