AntiSPAM & Restrictions

SPAM Submissions

All the form handles are by default filtered for spam using Akismet, the industry leader in spam detection.
The spam submissions will be discarded by default due to our Privacy Policy.
You can opt-in to save the spam submissions into your account to review them. Enabling this can be useful for debugging potential issues with legitimate submissions being marked incorrectly as spam.

Honeypot

The honeypot is a form field that's not visible to normal users filling the form. It's used to lure bot users filling it, but it should be left blank.
A form submission that has the honeypot field completed will be silently discarded.
To enable the honeypot fields go into "SPAM Protection" tab of your form settings and fill in the name attribute.

Honeypot tips
    Make it as legit as possible, trick the bots to fill it
    Don't use type="hidden" fields as most bots will recognize the trap
    Use text of email types and wrap the input in a div tag that's positioned out of the screen
    Use a common name attribute, i.e. name="url"
    Set tabindex="-1" so the visitors won't focus it by accident
    Set autocomplete="nope" so the browsers' autocomplete feature won't fill it by mistake
NOTE if you use a honeypot field you must declare it in you form settings, otherwise it will be ignored
