No Name question

I'm trying to navigate/study the Goodreads site and came across Meet People>Top Readers. There's a long list of people but I'll take the top example and perhaps someone can explain what it's all about.

First on the list is Liquidlasagna - 2,851 books read this week.
That's impossible, so what am I missing or not understanding?

Please ignore the book title - I had to fill in something or the format wouldn't let me post. I'm probably in the wrong section. Yikes it's confusing!!!
