hello, i'm from holland and i'm having a barnypok on my formulier as well. it's always the same name and with a link. My deutsch isn't well. but i understand you have got issues with that barnypok also. It's over ten times i get these forms from this "robot" Could anyone tell me if it is bad when it's sending these filled in forms? or only when i click the link(which i'll will never do)
However a captcha isn't a thing i would want to, i'd rather have a different security because i think customers will leave when irritated by those letters and codes you have to fill in.
PS: when searching on google on barnypok you'll get many sites that give the same email and link (i would not click these links only when you're sure it's not spam)
