What "school" inspects every single arriving Freshman? This read like an invented story. Additionally, there is not much overlap between Orthodox Jewish and African-American surnames.
Pretty much every single school that makes freshmen live on campus, which is pretty much every single school.

I'm going to make an educated guess you do not happen to live either in any of the urban areas with large Jewish and African-American populations or you at least do not happen to socialize with both groups. I can virtually guarantee you that you would have a very hard time sorting names in Bed-Sty, Flushing, Cheltenham, area around City Line Ave, Norristown, etc.
The policies to prop any group always bite because those policies presume that the other groups won't figure out how to profit off them and those policies typically do not have a way to stop a determined adversary.
