Let’s see how long this lasts.
Advice to posters: use Tor and/or EasyPrivacy.
Just to clarify: people should know that WordPress tracks the IP addresses of commenters. I absolutely do not intend to use that information in any way; but I wouldn’t blame you if you didn’t give much credence to an assurance from an anonymous person on the internet. So some slightly less apocalyptic and more nuanced advice: go to http://ip-lookup.net/ to see what information is carried by your IP address. If you’re comfortable (in the worst case scenario) with that information being associated with your comment, then post away. If not, then consider using Tor.
Update: comments with 2 or more links were being automatically flagged as spam. That shouldn’t be an issue anymore.
