If you have a naive loop like this you will quickly poison your dataset with e.g. thumbs downs because someone is unhappy with the latest frontend update, or teach models to not correctly refuse. I’m sure the pipeline is more sophisticated and in the middle.
Sure, but the point is more that once you submit feedback then the usual "opt out of using my data for training" no longer apply and at least that reply (and possibly whole conversation) can be included in training set in one way or another.
