I was facing the same issue and I made it solved one extension "Google Invisible reCaptcha"
Wait... I changed few modifications in JS code also.
After installing extension set Site key and secret in admin side and open subscription.phtml
YOUR-PROJECT/app/design/frontend/YOURTHEME/default/template/newsletter/subscribe.phtml
Add code just after Form Tag.
In the last of file add this JS Snippet.
It worked for me. Cheers if it works for you..
