Another one of these physical pole reversal docs from the clowns. See this has one major issue. If it has happened in the past then we would see a few things differently. In particular the mid-atlantic ridge magnetic stripes would look very differently. They would go all over the place randomly as opposed to being fixed, flip after flip, to the existing north-south that we have now. This is a scam document as was the previous one that came out a bit ago about the same topic.
