One of the things you could check is if they do direct posting.
What I mean by that if that sometimes a POST URL only is send. They
figured out the fields you have in your form and directly send a POST
with the appropriate fields.
You could check this in the webserver logs. Just look for the IP and
see if it only has a POST URL.
If this is the case you could implement a nonce on your form and check
it during the processing of the post.
A second idea is to check the IP of the visitor during the POST
process, with something like stopforumspam or project honey pot.
If you want more info let me know.
