Beavis, I was seeing a similar problem and I added a question to my forms that could only be answered by a real person. For example, "What colour is the sky?" You can then offer a drop down with several options, one of which is "Blue". There are several variations of this that you can use.

This is not exactly rocket science and the spammers may eventually catch up with it but since I first did it about six months ago all the spam has stopped.
