Thanks, Greek. I’m afraid that if I report these too much, they are going to start ignoring me. Good to hear from others. In any event, the PLONE.ORG main contact, has been great, issuing a patch and document to rid their installations of the spam. 2 new ones that I reported to him tonight are:
xhttp://python.psu.edu
xhttp://www.zopeuk.org
He has contacts for each installation, and has been great about getting the word out to them.
Thank you for reporting them ! It affects all of us.
