Name on a list, sure, fine. Pretty standard practice in big office buildings.

Running the guest list against some database of banned names, not so standard.

One reason it's not standard is that properly operating a list of banned names is very difficult, for the reason pointed out here in this post.

I didn't get this context from the post when I read it first - I guess this begs the question - was this a former employee of yelp or was it a true mixup?

It's a student, definitely not a former yelp employee or homeless person.
