Normally Akismet catches most of my trackback spam. This one slipped through one of my posts (http://www.celebslam.com/lunch-with-ali-larter-2#comments): # barbra streisand says: March 10th, 2007 at 11:08 am barbra streisand Please visit my site, click my ads and buy my crap Checked out his site (but don't click his ads). He's running Adsense: http://www.barbra-streisand.name
So report him/her/it to AdSense. Just click on one of the 'Ads by Gooogle' links and paste the URL where he/she/it left the comment. They'll sort the rest.
I agree. The wording of the post suggests it could be someone trying to get him/her banned. We will never know. Its best to send an email advising them and see what happens.
Well, this is a default comment message of Trackback Submitter - it can bypass spam filters like Akismet and others easily
