I have never really believed that SE would look at all the names submitted individually, because there are simply too many of them, and they need to investigate each and every single one of them. Consider how many staff there are in the task force - 20? 30? Consider how many servers there are, and how many names are getting submitted every hour.

They must have different systems - they may have a program to automatically detect characters that bypass certain mechanics, for example. As for names submitted, they may only look at ones that keep recurring.
