Toxic comments are becoming a major challenge to have meaningful online discussions.
This plugin uses a pre-trained toxic classifier from <a href="https://www.tensorflow.org/" rel="nofollow ugc">TensorFlow</a> to classify a comment as toxic. See more technical details on the quality of the model <a href="https://medium.com/tensorflow/text-classification-using-tensorflow-js-an-example-of-detecting-offensive-language-in-browser-e2b94e3565ce" rel="nofollow ugc">here</a>.
Once a comment is flagged as toxic, the comment is blocked and the plugin alerts the comment author and asks to modify the text before trying again.
In the default Settings->Discussion page you can enable the detection of toxic comments and define the threshold confidence level for the prediction.

Serious Toxic Comments

Very simple way to block some nasty comments to get to your blog. 

Also, good example of integrating ML in a WP plugin that I hope help others realize how easy would be to integrate other pre-trained models as part of cool ML-based WP plugins

Stop the trolls

Flag and block toxic comments from polluting your site with insults, threats, obscenities, etc.

This plugin performs image recognition when uploading images. It uses Google TensorFlow.js for image recognition.
Image recognition starts when images are uploaded from WordPress Media Library. Recognition results are automatically registered as captions of images.
