Which Captcha did you use? I noticed that bots are becoming very smart hacking simple captchas. I switched to Recaptcha and it seems to be pretty strong, but I am only using it for a couple of months. No bots as for today.

Did you already see the module
/modules/Campaigns/CaptchaValidate.php ?

And do you see this code in /modules/Campaigns/GenerateWebToLeadForm.php ?

 $Web_To_Lead_Form_html .="<script type='text/javascript'>
 function submit_form(){
  if(typeof(validateCaptchaAndSubmit)!='undefined'){
   validateCaptchaAndSubmit();
  }else{
   check_webtolead_fields();
  }
 } 
  

Strange, isn't it?
