If you have a look at his one and only post it is to query as to why a review would not post for him, 2 days later he submitted his very last review, maybe he just got pissed off with the system and decided not to bother anymore. Also shortly after a good many of his reviews were removed as they were second and third reviews of the same lady, he was over the 100 mark at that stage so Mr Fussy cannot claim that prize of reaching 100 reviews first.
Put all that together and somewhere in the middle may be your answer. I also hate to think it but maybe he has passed on to greener pastures, could be why he was so slow at typing
