Single answer
Your organization manages an online message board. A few months ago, you discovered an increase in toxic language and bullying on the message board. You deployed an automated text classifier that flags certain comments as toxic or harmful. Now some users are reporting that benign comments referencing their religion are being misclassified as abusive.

Your team has a limited budget and is already overextended. What should you do?
AAdd synthetic training data where those phrases are used in non-toxic ways.
BRemove the model and replace it with human moderation.
CReplace your model with a different text classifier.
DRaise the threshold for comments to be considered toxic or harmful.
