plone.app.discussion is the commenting system used since Plone 4.1. It was initially developed as part of the Google Summer of Code 2009 by Timo Stollenwerk (student) and Martin Aspeli (mentor).
- collective.autoresizetextarea (for auto-resizing the comment textarea while typing)
- plone.formwidget.captcha (for Captcha spam protection)
- plone.formwidget.recaptcha (for ReCaptcha spam protection)
- collective.akismet (for Akismet spam protection)
- collective.z3cform.norobots (provides a "human" captcha widget based on a list of questions/answers)
- plone.formwidget.hcaptcha (for spam protection by HCaptcha )
Note: not all of these may be compatible with the current version of plone.app.discussion and Plone itself.
There is initial documentation but it is outdated. You will still get a feel for how the package is structured though.
