I added custom captcha (simple math as slightly distorted pictures with audio alternative) on one of my forms, it prevents ~80% of spam submissions. less than 1% of spam passes, other ~20% are blocked on key words (like "sex", "passion", etc...).

Not sure why you’re telling me that. I’m not criticising CAPTCHA, my parent comment was.

I am just confirming that CAPTCHA still works against most basic bots.
