2.9.1 Using proxy to play tc is not forbidden, but we don't like it as it makes our work harder, so we are not supporting them. In fact, we block every proxy address we know.
--------------------------------------------------------------------
Some Internet Service Provider (ISP) used Private or Transparant Proxy.
If TheCrims block your 'default' ISP Proxy, please PM Abuse Crew or Support Crew.
You can use http://myip.danautoba.org/ to check your IP and Proxy Address
Just ordinary person that never play TC again..
