How I read your original message is that the I do not need to worry about contamination because the big labs already account for this and their methods are specified in the papers. I was dissatisfied by this response because I thought I had demonstrated working knowledge of these methods through my mention of contents of the training data as well as provided links to two relevant papers, one I was criticizing about how the decontamination method was far more naive than one might expect and the other was a work showing a significant amount of contamination.
