Closing Out Comments On Older Posts?

I switched to a new comment system (more on that later today or tomorrow) on August 7th, two weeks ago.

Since then I’ve received 22 comments that are not comment spam on the old typepad system. I haven’t kept count of how many total comments I’ve received on the old typepad comment system in the past two weeks but the past 24 hours was typical. A dozen comments and only one that I kept.

Comment spam on typepad is a huge problem. I’ve tried captchas, I’ve tried blacklisting IP addresses, I’ve tried blacklisting certain words. Nothing seems to solve the problem. I guess when I was getting thirty to fifty comments per day I could live with ten of them being spam.

But now that I am getting only a dozen a day, I wonder if its even worth keeping the old comment system open. I’ll certainly keep the comments that are resident there. They are as important as the posts. But I am seriously thinking of closing comments on all my posts made prior to August 7, 2007.

If you have something to say on one of those old posts, do it now.

It also suggests that Six Apart, the company that provides the typepad service, should allow bloggers to close comments on old posts. The vast majority of comment spam comes on old posts. The vast majority of legit comments come on new posts. I think one small but important step in managing the comment spam problem is to allow bloggers to close comments out on older posts.
