reCAPTCHA 플러그인?

I keep getting a bunch of signups, and they post jibberish posts (often meaningly random junk) that go to my review queue taking my time and DB space.

Is there something we can do? Maybe recaptcha will help? For example require recaptcha on login, posting, and commenting?

If they are actually human spammers copy/pasting jibberish (why would a human do that?) maybe a recaptcha will make them think twice about their time spend.

Is this what you’re looking for, perhaps?

아 네, 그게 맞는 것 같습니다.

저는 "hcaptcha"라는 용어를 구체적으로 검색하지는 않았지만, 시도한 다른 검색들(captcha, 스팸 봇 방지 등등)에서는 Customization > Plugin 카테고리에서도 이 결과가 나오지 않았습니다.
