This trolling is indeed fun!

Are you reading the same report as me? This guy was clearly flying on his FAA license during both crashes. The report clearly says "If the aircraft had been operated on the UK register, he would have been required to undertake training and a test to obtain a type rating." Ergo, the UK CAA could not have taken action against his UK license; but the FAA should have against theirs. How many times has this joker have to try to kill people before the Feds take action? As I said, out of sight, out of mind.
Bring all succh aircraft onto the UK register (or export them if they are not fit to be here). It will be safer for all!
