Although it is very early to make any conclusions, it is worth noticing that in the 24 hours since we instituted a small change to the .htaccess rules on one of the blogs we manage (talked about in previous post), the volume of spam comments being held by Akismet has dropped by almost 75%. Comparing the last 24 hours with the same 24 hour period over the last six weeks (all we have data for at this time) it seems the spam comments have dropped from around 240 a day to around 70.

Now, we are not for a second saying that blocking out LayeredTech.com is the sole reason for this reduction but it is the only change we have instituted. We will continue to monitor this and report any other findings as and when they occur.
