anti-spam – silent captcha – via registration form?
First: please DO NOT suggest the use of ANY form of visible CAPTCHA. My goal is NO visible CAPTCHA of any type.
Second: this is about s2Member “Registration/Profile Fields & Options.” I’m concerned only about blocking spam bots from registrations. No worries about comments (Thank You Akismet!)
Assumed: hidden empty input fields work well. Humans don’t see them and they stay empty. Bots fill in everything. A bot will fill in a tempting field … and if I can see a value in that field, I’m relatively certain it is a spam registration.
Question: s2Member’s Registration/Profile fields offer a lot of capability (THANKS), but what is the right combination of options to:
1. Make the field and its label invisible to the user.
2. Keep the field invisible from profile editing.
3. Ensure data entered by a bot IS visible to me … in the Users panel.
