Limit the number of entries that can be submitted by almost anything (e.g. user, role, IP, field value). Limit who, what, when, where, and how many times your form can be submitted. Create complex submission limits based on the submitting user, their role or IP, any field value submitted on the form, or the page from which the form was submitted.
