Non Captcha CONTACT Forms

[douglas]

The spam issue is being discussed for long time and still we didn't come to a final process or solution. I had discussions with jay and Silvester today and both have put forward some good suggestions.

We need actions here so that our clients get benefited of using these features without any more delay. Interesting things are noticed like most contact forms are without captcha which will leads to more convresions.

Find some of the options below and I suggest Jay, Silvester, Beniston, Jenni, Vipin Das have brain storming on this to come on a consensus.



Other option is;
"
1. Validate phone number field by accepting numbers plus () – and .
2. Make sure that spam filter is programmed and accept only post values.
3. Create a random token when the form is loaded and check it in the mail sending page using session
"
Please contribute your penny here friends!

Some suggestions follows:

* To use the reCaptcha plugin which Facebook, Twitter kind of site uses. This is one of the powerful captchas.
* To use a flash based captcha in which the Captcha text would appear inside the flash image (could be with some animation)
* To use calculation based captcha. The use can be asked to answer some simple question to pass the validation
* Block a ip for some hours if the submission count exceeds certain limit within a particular limit of time.
* As mentioned in the 3rd point, create a random token and validate the posted token with the session token

Found this a good read and solution -

We can also check mx records to check that the email domain is valid (not email address) - PHP Email Validator -
