After working through the code with Tim for a few hours this
afternoon, the TorBlock extension has been enabled on Wikimedia.
The TorBlock extension will override local IP blocks to provide a consistent treatment of tor. Currently, this involves allowing only logged-in users to edit, and requiring tor users to have 100 edits,
and a 90-day-old account, prior to being autoconfirmed.
Hopefully, this will provide a balance between allowing users to edit through tor without the difficult process of granting per-wiki IP block exemptions, and preventing pagemove vandals (such as the user
known as 'Grawp' on English) from using Tor for vandalism and so on.
