DMCA Complaints

Unfortunately, the Tor network is sometimes being abused for file sharing. This hurts the network, and Bittorrent over Tor isn't a good idea anyway.

If you run a Tor relay that allows arbitrary ports to exit, you sadly cannot stop this from happening. Many ISPs and data centers are scared over receiving automated notices by Bittorrent scanners like those run by MediaSentry (now Peer Media Technologies). Because anyone can file a DMCA complaint and send such notices, this leads to the absurd situation that you can force the takedown of almost any server, even outside US jurisdiction - and even though a Tor operator is perfectly protected thanks to DMCA §512(a) (and similar laws outside of the USA).

So far, we were out of luck about contacting MediaSentry about their reports. We reply to every single one of them, and we tried to get in contact with them over basically any email address we could find. For some funny reason, Peer Media Technologies still uses the name “MediaSentry” and the MX

Dear Peer Media Technologies, 

We do not keep customer usage information. As a German non-profit
organization, we are bound to the German Telemediengesetz
("telemedia law") which prohibits logging of customer usage data unless
required for billing purposes (TMG section 15).

Our systems do not host content and fall under section 512 of the DMCA
"Transitory Digital Network Communications" and similar laws. We do
not control or select the transmission, routing or provision of 

We are not interested in supporting criminal activity. To the contrary,
our networks are being used to run Tor exits. Tor is a research project,
funded by the National Science Foundation and previously DARPA (among
others). Its primary goal is to provide people from hostile environments
with encrypted and uncensored access to the Internet. For more than a
third of the worlds population, the Internet is being either filtered or
monitored. Every day, activists and bloggers are imprisoned or
threatened for what we in the western countries see as a Human Right.

There are usage stats on the website that show that
more than 500,000 users from China, Iran and similar regimes use Tor to
access the Internet every day.

At, we offer to run Tor nodes for people and
organizations willing to help monetarily.

You can find more information specifically about abuse scenarios and the
legal situation at

Thanks for your understanding. If you have further questions, feel free
to contact us again.
