Random Name Remover

This is more of an open answer question, rather than a specific coding question.

I want to know if anyone has ever come across some sort of algorithm to remove random names from a list. Let's imagine the following example:

List

If I visually look at the list I know exactly which ones are randomly created and which ones have a human behind it. I marked those in red.

I wonder if you guys have any ideas of how to go about coding some sort of algorithm to try to sort them out.

Any input greatly appreciated!

Best Regards
