Tor DNSEL Rewrite

by Harry Bock for The Tor Project/Electronic Frontier Foundation

The TorDNSEL project is concerned with identifying individual hosts as valid and accessible Tor exit relays. Each Tor exit relay has an associated exit policy governing what traffic may leave the Tor circuit and go out as requests to the internet. A public database that can be easily queried or scraped would be of huge benefit to the Tor community and to services that are interested in whether clients originate from the Tor network, such as Wikipedia and IRC networks.
