A couple of the blog owners have let me know about readers getting a 410 HTTP error when they try to post a comment. It doesn't happen consistently, but only if your comment text matches one of the spam-test patterns I've defined in the Apache web server's mod_security module.
If you get a "410" error on a comment, drop me a note, and please include the text of your attempted comment. Also, if you can provide your IP address and the time of your attempt, it'll help me find information in the server's error log. Once I find which pattern is triggering the error message, I can fine-tune the pattern rule to avoid this "false positive".
