BiGDUG Posted April 10, 2007 Share Posted April 10, 2007 Recently we have been having trouble with our mailform being hammered by spammers. I am fairly certain that they are accessing the form outside of the site because the emails aren't valid (see email contents) and there is email validation on the form. Name = 144957a7-2ca2-4130-9f16-f715da818ed4 Email = 144957a7-2ca2-4130-9f16-f715da818ed4 Telephone = 144957a7-2ca2-4130-9f16-f715da818ed4 enquiry = 144957a7-2ca2-4130-9f16-f715da818ed4 Comments = 1 waitfor delay \'0:0:20\'-- Reset = Reset 02/04/07 - 20:43 I am looking for a way to reduce these spam attacks but do not want to go down the route of using captcha as i feel this may dissuade users entering forms. Is there a way of ensuring that a form has only been submitted via a valid refferer. Any other suggestions and ideas gratefully received.

BiGDUG Posted April 10, 2007 Author Share Posted April 10, 2007 I would like to avoid using captcha if possible as i do think they raise useability issues, also the forms we are talking about are only catalogue requests and general contact forms, therefore if you put obstacles in the way genuine users are less likely to complete the forms.

Asheh Posted April 10, 2007 Share Posted April 10, 2007 Ask the user a random and simple question which may relate to the form details, this way if its answered wrong the form isnt submitted?
