Re: Witango-Talk: [OT]how to discourage spam robots from forms

we've all seen it, but not sure how to conjure up that kind of function. Is there a graphic generating program?

No big deal. It gets a handful of messages a day. All of a sudden, the form starts to get spam submissions. Lots of them. Each one from a different IP address. They are all of the same form and have an argument for each field in the form, but the content varies. The most common email address entered is at cashette.com , a spam filtering service. Any ideas how to combat this kind of stuff? ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf ________________________________________________________________________ TO UNSUBSCRIBE: Go to http://www.witango.com/developer/maillist.taf
