Phoca Guestbook v3 Gets Tons of Spam, Google ReCAPTCHA v3

[stanislawru]

I used Phoca Guestbook v3.0.12 with Google ReCAPTCHA v3 (via “Options” > “CAPTCHA” > “Enable CAPTCHA” = “Joomla Default Captcha” and Joomla > “System” > “Global Configuration” > “Site Settings” > “Default CAPTCHA” = “CAPTCHA – Invisible reCAPTCHA”) and received tons of spam just like Google ReCAPTCHA v3 was simply ignored by Phoca Guestbook… :-(?)

Today I wanted to check the CAPTCHA options once again and found that the used value “Joomla Default Captcha” was completly removed from “Options” > “CAPTCHA” > “Enable CAPTCHA” – why?

And how can I use Google ReCAPTCHA v3 now?

Hi, for now there is no option for reCaptcha 3 as it just didn't work. Did you read this article:

https://www.phoca.cz/documents/3-phoca- ... -from-spam

Mostly, any captcha method is weak protection so it is good to see other options.

I will try to see if I can implement the Joomla built in reCaptcha, but the problem, the implementation is not easy.

…For now there is no option for reCAPTCHA 3 as it just didn't work… I will try to see if I can implement the Joomla built in reCaptcha, but the problem, the implementation is not easy.

I hope you will succeed at least with https://contactform7.com/recaptcha/ or https://contactform7.com/recaptcha/ (though Contact Form 7 is a plugin for WordPress, it is also written in PHP so you can see how it is implemented).

However, what of the 3 left methods (“Standard CAPTCHA”, “Math CAPTCHA” and “TTF CAPTCHA”) would you recommend as the best for now?

Hi, I use standard captcha here:

and get no problems with spam (of course there is human spam but this is very hard to prevent from)

Thanks for the recommendation! I have successfully switched to this type of CAPTCHA, and am quite happy with the result! :-)

However, I would be glad if you implement Google ReCAPTCHA v3 support in Phoca Guestbook and notify me here. Thanks in advance!

Ok, added to feature request list.

Hello Jan,
Would you consider implementing Google ReCAPTCHA v3 support?
Or, even simpler, a new option: using Joomla's global reCAPTCHA settings.

[Jan]

Hi, in past, there was support for core Joomla Captcha plugins but the Joomla core feature changed, so this non functional feature was removed.

I have it in feature request list to implement the core captcha again, but really hard to say when I will find time to do it (there is a lot of changes in Joomla core repeatedly, so it takes some some to adapt to these changes).
