Stop Bots From Filling Aweber Form

Question

I have a bunch of Aweber forms with just a name and email field on my site. The forms are getting a lot of spam registrations. Is there a way that I can prevent these bots from filling my forms?

<form method='post' action='http://www.aweber.com/scripts/addlead.pl'>
  <div style='display:none;'>
    <input type='hidden' name='meta_web_form_id' value='-----' />
    <input type='hidden' name='meta_split_id' value='' />
    <input type='hidden' name='listname' value='-----' />
    <input type='hidden' name='redirect' value='-----' />

    <input type='hidden' name='meta_adtracking' value='-----' />
    <input type='hidden' name='meta_message' value='1' />
    <input type='hidden' name='meta_required' value='name,email' />
  </div>

  <ul class='vMenuForm'>
    <li class='lname'>Name(<span class='red'>*</span>):</li>
    <li class='name'><input type='text' name='name' value=''/></li>
    <li class='lemail'>Email(<span class='red'>*</span>):</li>
    <li class='email'><input type='text' name='email' value=''/></li>
    <li class='submit'><input class='button' type='submit' name='submit' value=''/></li>
  </ul>
  <div style='display: none;'><img src='http://forms.aweber.com/form/displays.htm?id=HKwMHMzMTCyM' alt='' /></div>
</form>

This is one of the forms as it exists now. Any ideas?

Answer 1

I would create the form dynamically using javascript. This should keep the simple Bots from posting your form. Though this solution has drawbacks like your users must have javascript enabled.
