I pretty much agree with this although it isn't a hard and fast rule. Generally speaking, the sign name isn't given by A deaf person; it's more like a general consensus among many deafies, based on some sort of personal or physical attribute of the hearing person over a length of time. I'd also add, it seems like it would be pretty difficult to assign a name sign for someone here on this forum unless there's something about them that truly stands out and then the sign would probably stay right here in this box and the person would have another sign name IRL.
