Information on Open Proxy
a) What are Open Proxies?
Open proxies allow anyone to establish a TCP connection to any location via the proxy, effectively hiding the connecting IP address. An open proxy can be used by a spammer to anonymously send out spam, using the resources of the owner of the proxy. Use of open proxies complicates both filtering spam and tracking spammers.
