The palmit.com commenting system is back up – I pulled it down because I was getting burried in comment SPAM. Please try not to hit the server all at once ; )
What did I do to reduce the SPAM volume? I spent some time further customizing and configuring the already powerful SPAM blocking features included with MovableType 3.2. Additionally, I installed Brad Choate’s free MT-DSBL plugin. MT-DSBL uses real-time DNS lookups to determine if the commenter’s IP address is listed as an open proxy. I configured it to automatically "junk" any comments coming from an open proxy and this seems to be helping. I also spent some time reviewing my collection of junk for popular keywords – which I added to my keywords filter.
For the moment, my comment SPAM volume has been reduced to a manageable level.
