Why did I get this junk information?

Hi, administrator,

Thanks for the good work.

I used ChronoForms_V3.1_RC5.3 creating a contact form, which asks visitors to type in their names and email addresses. The form works greatly. But recently I have got three contact emails info like the following:

Name:
jnhAWsnAVlTZgtRHKuK
E-mail:
OoNYSmEErsY

It looks like someone entering junk information in and submitting. How can I avoid this? When I set up Validation property for “Email address” field above, I selected both radio box “Required” and “Email” as tutorial told. I wonder why “OoNYSmEErsY” could go through. It is not even an volid email address.

Thanks.

Hi,
It would appear that you've caught the attention of a spambot😟

The validation you've enabled is a simple client-side javascript. Any browser or robot that does not honor javascripts will be able to submit whatever they'd like. Thus, this feature is really intended to help visitors double-check their data before submitting, not to prevent spam.

A first step to stop spam would be to enable/implement the image verification feature of chronoforms (aka captcha). To further improve the protection, you could use the serverside validation option with some custom php-code to test the submitted data.
You'll find plenty of threads how to use both on the forum - but if you get stuck, don't hesitate to ask for further help.

Thank you so much,Fredrik.
