TorNodeBot is a bot that monitors the Tor network and ensures that Wikipedia exit nodes (those nodes in the Tor network that can be the last "hop" and route data to its final destination) can not edit, in accordance with our policy on Open proxies. The TorBlock extension is supposed to handle this automatically, but tends to miss several exit nodes and goes down on occasion. TorNodeBot fills in the gaps left open by the extension.

This bot runs continuously and applies blocks when all of the following 3 conditions are met:

:# The node is present in the Tor directory service as an exit node router

:# The node is responding to requests and can route to Wikipedia's sandbox

:# The node is not blocked already by the TorBlock extension

When all three of these conditions are met, a temporary block is placed on the node.
