Some time ago, I added a captcha to the feedback-module and the submit-module. I've done this to prevent people robots from spamming me, as this is happening more and more.

Per day I see around 45 attempts to automatically post something. One other way to deal with automated spam, is renaming the feedback-module to something else or just adding a word that has to be retyped, if you're original the scripts won't work. For now, I have added the addresses to the ip-ban table nuke_banned_ip, so they can't try again. I'm working on a script that checks the apache logs for POST messages, filters out the feedback and submit pages and then sorts the ip-addresses. Of course I would have to manually filter out the messages I really received. To start of, I would use something like

grep POST /var/log/httpd/access* | egrep 'feedback|submit' | awk ' { print $2 } '| sort -u

These are the ip-addresses of the FAILED attempts to send some feedback to me in december 2006:
