[cobalt-users] How to stop form spamming!

["Casselman, Chad" <chad.casselman@xxxxxxxxxxxxxxxxx>]

I have a site that allows people to submit a form and it posts their site
information for me to review and add their site to my site.  Well somehow (I
think with cgi) someone is posting hundreds of hundreds of links without
touching my pages.  I have it logging all environment variables when it is
submitted but I can't tell the difference between one of this spammed
submissions and a good one.  I know it is a script because the stats program
is not counting any hits for all these submissions.

How can I stop this?

Please help me stop this spamming,
chad
