My favorite part of this blog is reading the comments from you folks. One individual, however, has made it his life's purpose to keep creating fake profiles and spamming the blog. It is time-consuming and demoralizing.
Because of this, I have cranked up the level of security to require everyone to authenticate their email. When you try to post a comment, it will (one time only, assuming this works!) ask you to authenticate your email address. It should send you an email, and once you click the URL, you should be good for life. I am hedging my words here a bit, because you never know if there's a bug in Disqus I'm not anticipating.
Even if you have nothing to say, try to post a comment here to make sure it works (not everyone has to do this; I'd just feel more comfortable if I see a few dozen comments successfully posted).
Hopefully this will be the end of Ned.
