Do you know of a working alternative and have some hands-on experience
you can share with us? That'd be great! :-)

I have found some alternates can provide captcha without relying on Google’s online service, all of them are FOS:
https://github.com/mewebstudio/captcha
https://github.com/dchest/captcha
https://github.com/Gregwar/captcha
http://dice-captcha.com/
http://jcaptcha.sourceforge.net/
http://www.phpcaptcha.org/
http://www.sweetcaptcha.com/
Alternatively, we can also get source from Google to build our own captcha:
https://github.com/google/recaptcha/releases

Do you have experiences wrt. their detection rate? A properly working
captcha is quite important given the amount of spam we regularly see, so
if we have insight into their detection rate, that would avoid parts of
own tests. ;-)

Would this be working in China, or is this blocked as well?

Then I’m out of idea.

If you create your own captcha based on this, but not send any request to Google, it would be work and not being disturbed by GFW.

- Subject changed from Replacing reCAPTCHA on Ask LibreOffice to Replacing reCAPTCHA with self-hosted version
- Assignee set to Guilhem Moulin
- Target version set to Qlater
I'll assign this to Guilhem
However, not sure when we will find time for this - if a volunteer wants to look into it before, happy of course to give them access to our testing site :-)

Thank you, I hope you can avoiding GFW soon.

LO Extensions and Templates website should do it too for Registration form.

Guilhem, I wonder whether that is some EasyHack and/or volunteer task to look into, or is it so trivial that it needs no investigating, but merely doing? (which then is limited to the admin group of course due to access requirements)

Something for the next infra call?

- Priority changed from Normal to Low
We're currently using reCAPTCHA v2 as plugins to MediaWiki, Askbot, Plone (https://extensions.libreoffice.org) and Silverstripe (https://libreoffice.org); switching to another captcha solution requires that we find and configure a working plugin, or possibly develop our own if there is no such plugin.
The WebSSO system uses a self-hosted captcha solution, and once we change the auth method of the above services their frontend for account creation will disappear. I'm thus lowering the priority per the Nov. 21 infra call. If there is a working plugin which can replace reCAPTCHA in Askbot I can offer to deploy it, otherwise I'd rather spend my time on the SSO migration than attempting to glue the various bits together :-P

Still relying on Google server while answering, so I've to seek the way to fanqiang for this. :-(

- Priority changed from Low to Normal

Let me try to prioritize that higher, it seems to be causing issues for many
Let's talk about this in a next team or infra call

Got hinted at http://www.karlgroves.com/2012/04/03/captcha-less-security/ which might provide further insight
Updated by Krasnaya Ploshchad’ about 6 years ago
Looks sad that reCAPTCHA has security holes.

We had some discussion on this topic, but I don't recall the exact outcome. IMHO not all services support self-hosted ReCaptcha, and/or it was not as effective.
What are our options, what do other projects do in this regard?
Does it make sense to have something self-hosted for a set of services/IPs only?

- Target version changed from Q2/2018 to Qlater
We discussed this recently in the team call, but there seems no real effective ReCaptcha alternative around
We should revisit the need for the ReCaptcha in the various sites (i.e. is there a concrete need to handle antispam that way), and disable where it's not required
Anyone has insight what other FLOSS projects do for ReCaptcha?

If there are no good alternates to reCAPTCHA, and Google’s releases doesn’t works well on our server, we can close this task in favor of task #2774.

- Subject changed from Replacing reCAPTCHA with self-hosted version to Replacing reCAPTCHA
Is there any site still relying on reCAPTCHA? I discovered a good replacement of that, and it doesn't be banned by Chinese Communist authority.

- Assignee deleted (
Guilhem Moulin) - Target version deleted (
Qlater)
Most services moved to SSO, so not relevant for these anymore
Relevant only for AskBot, which likely will be replaced in the near future as well
New extension site temporarily using it, will soon allow authenticated users to bypass

This bug seems affect the LibreOffice Extensions website, which requires captcha for me before submit a comment, otherwise:
Please answer the captcha, if you do not see the captcha please enable JavaScript
