One thing I value about this blog is that I still have loyal readers despite my long hiatuses and delays in posting. I can always count at least one or two comments on a post at minimum, and often from people who have never commented before. This is possible because of the open commenting policy here, but that’s also a weakness in that it allows spammers a toehold. The spam filter has been doing its job but lately more and more are sneaking past the defenses, and I am worried that it will get worse form here.
The question is the usual one facing a blog with a nascent community. Do I limit comments to registered users only, thus slamming the door on the casual readers who will probably never comment again? Or do i leave the door open in the hope that signal stays higher than noise?
I guess I could also install a plugin to auto-close old comment threads to see if that mitigates the problem. And there are math captcha plugins like I used before. But these are just symptomatic solutions.
So, lets see what you all have to say about it. What would you prefer? Whats your advice?
