Twelve months ago from today this blog was being inundated with blog spam. After trying capcha's and other kinds of filters, I turned to Akismet. Installing it was simple, although it did require getting a WordPress.com account. Since that time, the volume of spam I personally deal with has dropped dramatically.
As of this morning, Akismet has trapped 332,579 spam comments. That's more than 911 per day all year. Currently, more than 2,000 spam comments get entered daily on this blog. It's more than any human being could manage manually,ever.
Thank you, Akismet, for making this blog manageable.
