If you're not careful, you're training your algorithm to continue promoting a bias... Perhaps one that you're not even aware of... Or perhaps someone else's bias imparts a bias on your algorithm (like turning your chat bot into a Nazi sympathizer -- an extreme example, but it could also be someone else's refusal of loans to minority groups, and your algorithm might look at debt ratio as a factor) You can't keep assuming your inputs are always good... and while it may be okay to do some automated retraining, you really need a skilled person to revisit the inputs/outputs...
