If he wants to collect stats about misbehaving code then presumably he needs reliable stats. Arbitary user set names are not reliable and judging by app vendor behaviour in the proprietary space with other such examples they will actively name their blockers in a manner specifically intended to hide the cause so as to 'reduce support costs'. Its a waste of memory (especially if I create a million of them with a long name for fun). It's all an economic system, proprietary app vendors are in it to make money, some will therefore game the system and the rest will be forced to follow to keep their playing field fair.
