I recently came across [this question][1] which has been marked as a duplicate. What's strange is that this question has been marked as a duplicate by the [Community user][2]:

[![marked as duplicate by Community][3]][3]

How can Community mark a question as a duplicate if he's not a real person? Was it a moderator who marked the question as a duplicate? Was it an anonymous user? Or did something else happen?
