Form spam blocking

No annoying captcha needed!

Just add a few lines of code to any form's HTML and you're all set. Each time your form is submitted, it gets sent through our bot filters before it gets forwarded where it needs to go.

Currently in beta: The more our bot filters are used on forms, the more we'll be able to fine tune results. If you run into any issues, please contact us.


Below are the needed code snippets to add within your <form> tag:

  1. Set your form's action to
    <form method="post" action="">
  2. Add hidden input for the original action for your form:
    <input type="hidden" id="useraction" name="useraction" value="[ACTION_URL]">
    Change [ACTION_URL] to the URL of your form's action.
  3. Add hidden input for spam check:
    <input type="hidden" id="enablesubmit" name="enablesubmit" value="">

And then the Javascript that should be placed anywhere after your <form> tag:
<!-- Indie Aisle - connect directly to your audience -->
<script src="" defer></script>
<!-- / Indie Aisle -->

Privacy practices: We don't store, or use your form's content in any way. Only block the bots. Content is forwarded directly after the bot filtering.
