Please, be advised that in order to 100% prevent bots from submitting your form you'll need:
Step 1. Rename the form Script
Just rename your submitting script from submit.cgi to submit_secret.cgi (for example) and add this url to our system.
Step 2. Check for your private key
After registration you will receive 'Private Key' string, it will be passed to your script (if your form uses POST method), check for _smpost_private_key value in POST request to validate you've received non-bot request.
PHP Example (when validating the form submition):

You should check that request to your submit script (the one mentioned in action field of your <form> tag) is made from our ip zone: 88.214.209.*
PHP example (place in message post part):
