I've been using the hub to track player population activity across servers to generate a graph showing times when servers were most popular, but someone pointed out to me that the numbers were off, it turned out that I was not accounting for invisible players, so I thought to myself this should be an easy fix, It turned out that the only way I could figure out how many invisible players a server had was to use a regex search on the standard HTML format to find the "(number) private" string when you would expect this data to be available in the raw text format.

For anyone wondering the raw format for the hub can be found by suffixing "?format=text" to the URL.
