Es gehört sich für einen Exit-Node Betreiber eigentlich nicht, den darüber laufenden Traffic in irgendeiner Form zu filtern. Das widerspricht den Grundsätzen des Tor-Netzwerkes. Ich habe für meine damaligen Exit-Nodes das unten stehende Template für Antworten auf Abuse-Meldungen verwendet, zumindest bei He**ner viele Male ohne Probleme.
Zusätzlich fand ich es angemessen, den ausgehenden Traffic auf die im Web verwendeten Ports zu beschränken, also HTTP, HTTPS und DNS. Dadurch lassen sich viele Dienste erreichen, du sperrst allerdings unkonventionelle Services wie z.B. Torrents aus.
INTRODUCTION
===============================
The IP address XXXXXXXXX is a Tor exit node.
https://www.torproject.org/overview.html
You can find more information about this node by using the Tor atlas page:
https://atlas.torproject.org/#search/XXXXXXXXXX
SUMMARY / EXPLANATION
===============================
There is little we can do to trace this matter further. As can be seen from the overview page, the Tor network is designed to make tracing of users impossible. The Tor network is run by many volunteers who use the free software provided by the Tor Project to run Tor routers. Client connections are routed through multiple relays, and are multiplexed together on the connections between relays. The system does not record logs of client connections or previous hops.
This is because the Tor network is a censorship resistance, privacy, and anonymity system used by whistle blowers, journalists, Chinese dissidents skirting the Great Firewall, abuse victims, stalker targets, the US military, and law enforcement, just to name a few. See https://www.torproject.org/about/torusers.html.en for more info.
Unfortunately, some people misuse the network. However, compared to the rate of legitimate use, abuse complaints are rare. https://www.torproject.org/docs/faq-abuse.html.en
NODE RESTRICTIONS
===============================
This specific node only allows outgoing connections through the following ports: 53, 80, 443. Therefore it is not possible to send spam or distribute torrents through this node. Sadly, this port limitation is the only thing we can do to limit the probability of misuse of this exit node.
BLOCKING TOR NODES
===============================
The Tor project provides an automated DNSRBL for you to query to flag visitors coming from Tor nodes as requiring special treatment: https://www.torproject.org/projects/tordnsel.html.en. The same list is available through the Tor Bulk Exit List: https://check.torproject.org/cgi-bin/TorBulkExitList.py
