Toxic comments are becoming a major challenge to have meaningful online discussions.
This plugin uses a pre-trained toxic classifier from TensorFlow to classify a comment as toxic. See more technical details on the quality of the model here.
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.
