odd email results - CF compromised?

Hi, I’m fairly new to CF and using the form built via wizard.
Even though I made email/name required field occasionally we get odd email results submitted though the form.
When someone bypasses the required fields and they’re able to submit the form can I conclude that CF is being compromised?

Here's the link to quotation form
And here’s an example of email results:

Hi kontech,

The email field isn't required (just that if there is an entry it's a valid email address).

If the spammer's browser has JavaScript disabled then the client-side validation will not be effective.

If this is a major problem than add an anti-spam link and/or server side validation.

Bob,
Thanks for the prompt response.
I didn't realize that required fields use client-side validation. I know now.
I was refraining from using captcha as it can become a double edge sword.

Hi Matt,

The built-in validation is all JavaScript based - that works 99% of the time with 'normal' users.

It easy to add a little serverside validation to check a couple of key fields. See the eaxmple below the server-side validation box.
