You would have to ask them that - as you can see, its certainly no secret that he was a scam artist and fraudster. He fabricated his trial data many times over many years. Perhaps they choose to preserve online versions of their paper journals in exactly the same format as the paper ones were published. In that case there is usually a retraction of any dodgy papers that have already been published in future versions. Not so helpful if you don't know about it and come across retracted papers via search engine.

Where the underlying info is good and reliable, then use those papers to support your requests. Just don't use anything by Reubens or rely on any parts of future papers that rely on references to his research.
