Some 'spammers' use scripts that seek out <form ... method="post" ..> tags and then issue POST requests to the action= attribute. In some cases this results in 'posting' content of some sort to web sites (eg comment / forum spam). Or it generates E-Mails to someone who might respond to the content. In other cases it is a form of denial of service attack, overwhelming the server. In some cases, it is totally 'mindless', eg generated data using field names as a guide as to what to generate: such as random E-Mail addresses for an field with a name like 'email', and so on. > > Perry -- Robert Heller -- 978-544-6933 / hel...@deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org https://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: https://mail.python.org/mailman/options/mailman-users/archive%40jab.org
