[Full-disclosure] Proxy Detection

[Andrew A]

There are Tor DNSBLs, which have been incorporated into popular blacklists
such as SORBS. Since you can poll the directory server for a list of exit
nodes this is rather easy to compile. Tor does not give an x-forward-for.

To avoid getting hosts that have been blacklisted, use newer proxies that
haven't been absorbed into blacklists yet.
