The amount of comment spam has reached intolerable levels: spam comments far outnumber legitimate comments and moderating them is taking an increasing amount of time. Therefore, I have reluctantly installed a captcha to try to bring the problem under control. I'm using the NUCaptcha plugin, which features moving letters that are easier to read so I'm hoping that this won't inconvenience folks too much.
The captchas appear only to unregistered users so if you are a regular commenter, it's probably worth your while to register and avoid the hassle of dealing with captchas. Again, sorry for the inconvenience. As usual, a few bad actors ruin things for everyone else.
Update: inconvience → inconvenience
