Basically, K. Krogh is claiming that G. Forst would be...Lorenzo Iorio! It sounds really comic and clearly motivated by simple envy by Krogh who has published just one (1) paper in peer-reviwed journals with respect to Iorio (more than 100). Indeed, Iorio has always demonstrated that if he has something critical to write about a test (specifically, the LAGEOS-LAGEOS II tests by Ciufolini) he always acts clearly and explicitly by publishing papers on peer-reviewed journals! Moreover, Iorio has never published anything about the gyro experiment of GP-B! Instead, it is more likely that G. Forst is Ignazio Ciufolini (often criticized by Iorio in numerous peer-reviewed papers) or some fellows of him, as clearly suggested by the arXiv moderators themselves. Moreover, on Wikipedia, at the voice frame-dragging, some years ago a comic editing war occurred, when Italian guy(s) systematically and repeatedly removed all the references by Iorio which were replaced soon after. There are no proofs, but the identity of such guy(s) should be clear..
