Sharegod- I suspect the poster giving such a warm endorsement of Hochman/Arad was Hochman/Arad himself or a close associate.
I note that they assert that "Dr. Arad’s family background and educational achievements are a matter of public record". I think that assertion is highly questionable. If anyone can point us towards the relevant public records I'm sure we would be interested, as also with the explanation of why Arad appears to have used at least four different surnames during recent years (Hochman, Hochman Bilbao, Arad, Arad Hochman).
Then again maybe any such probing would merely elicit the response "you ask the most beautiful questions".
