Is there a built-in way to prevent spambots from attacking my forms?
Not currently, unless you add some client side validation to your form inputs, but this is certainly an area I’m keen to explore…
I’ve been reading about the hidden input technique.
Theoretically bots fill all the fields in a form and thus, you can detect them by hiding one or more input fields that real humans won’t see. But I don’t know how this would work with Forge’s form system.
