Simple Spam Protection
Helpful provides simple spam protection by adding a hidden field for the website to the feedback form. This field is not required by Helpful. However, spam bots fill the field and if they do, Helpful does not save the feedback.
This does not affect Helpful’s polls, since no form is used there. You can also disable the spam protection using PHP. All you need to do is to address the helpful_simple_spam_protection filter.
