I had never thought about it until Takayuki suggested it, but adding an acceptance box to your custom CF7 form is just one more barrier between you and those wish-they’d-give-up spammers.
Not only does it serve to remind the site visitor of your Terms of Service (you do have one, right?), but that one extra step, that manual clicking in the box, is another way of screening sincere parlay-ers of your website information from those with less than sincere intentions.
This is an example of a quiz and an acceptance checkbox. Nothing that hard for your site visitor, one extra step of protection for you. Most people will appreciate your efforts to prevent spam.
