Anti-Captcha is a transparent spam solution that does not require any end-user interaction.
Spam isn't present absolutely!
For my personnal need I extended the anti-captcha plugin simply by adding an add_action() and the corresponding function : now my booking forms are protected and it works like a charm, out of the box.
Thank you !
I have this plugin installed for a couple of years now, and only need to delete one or two spam comments that slip through. No captcha.
