Here are some approaches that should help to reduce form spam 
without introducing accessibility problems.

Also, if it's an internal-only form that doesn't purport to take in 
confidential responses, you could always add cookieauth to it, so 
users are forced to login. Yes, it *could* be an extra step for your 
users, but it's the simplest approach I know of, if you don't 
already have a set of form handlers you can use.
