    We have been receiving 100s of form spam even on validated forms. I know there is an image validation php script that works unfortunately I am not much of a programmer and some of our sites run on servers that do not support php.

    Could we disallow this file or folder in our robots.txt? Is there another work-around that anyone is aware of?

    All fields are required, email field is validated but the bots have found a way around that.

    thanks

    I seriously doubt anything in the robots.txt file will stop a malicious bot.

    Although not as good as image verification you may get some success by posing a question and then checking the response. Something like 'whats 2 + 2?' or 'are you human or machine?' may work. You'll probably need to change it regularly but it is an approach I've seen used elsewhere with some success.
