Liz Crocker is a 33-year-old graduate student and the mother of a one-year-old. Her days are spent writing a dissertation, teaching a course to PhD students at Boston University, looking after her child, and —oh yeah — dealing with internet trolls.

Why? Because Crocker is also a Reddit moderator for the main science subreddit — /r/science, which has 9.8 million subscribers. Being a Reddit mod for /r/science is a title that only belongs to Crocker and 11 others, and comes with absolutely no pay.

We recently visited Crocker at BU in order to get a better idea of what being a Reddit moderator is really like.
