Neville ChaimBerlin – referring to a choshev Rav with a nickname or the like shows a lack of reverence. Kavod Rav is very important and “JB” is not a respectful title. It’s something you’d call a friend, not people you need to show respect to. Imagine calling your father or mother by their initials.
Regardless, this unbecoming title stuck and that is how he is referred to by many. Among his talmidim, however, he is also referred to as “The Rav”.
The most important point to take note of is that this title, “JB”, was NOT introduced by the Black Hat community.
y1234 should consider apologizing for insinuating that YWN had any intention to disparage his name.
