Failing to Stop Comment Spam
For the past week I’ve been getting a ton of comment SPAM, and it doesn’t want to stop. I’ve got the Akismet and Spam Karma 2 plug ins up and running, and SK2 is set on MEAN! Unfortunately, as you can see:

I’m getting hit by MP3 Ringtone spammers. The problem is that I’ve gone and put this spammer’s domain on the blacklist, but it doesn’t seem to be working . . . they are smart enough to be using multiple IPs to post the messages, and seem to be using some kind of exploit on the Share This plugin:

If you look at the above image, you’ll see that the posts aren’t trackbacks to an outside site, but to my site’s “Share This” pages. Of course the author’s link goes back to bla-bla-bla.us.
Tracking Down a Spammer
When I did a WhoIs search on the domain, I got what seemed like a nonsense profile, until I saw the contact email domains@sslpayments.com, which is run by Andrew Kartashov, a SPAMMER out of Moscow, Russia. (Thanks to the Spam Huntress for the info on this guy)

It looks like the domains are registered and hosted by eNom.com. I put in a message to them to see if they’d be helpful at all in dealing with this.
What about the ShareThis PlugIn Exploit?
I’m not sure. If anyone has any ideas about what I can do from here, let me know. I’ve always been able to handle spam on site with the 2 plugins I mentioned earlier, but this is just geting annoying now!
If I have to stop using the plugin to handle the situation, I guess I’ll have to . . .
Any thoughts?
