I think this should be reopened. The issue is that the pseudonym appears to be the same for a given user across the entire platform, rather than uniquely reshuffled for each post/comment thread. This means that once a user's real identity and pseudonym are connected (for example, by accidentally revealing it to others or by inference), classmates effectively know who that user is.

Aayush Agrawal, the idea behind anonymous and pseudonym is that you can still hide your real name from your classmates and instructor while other people can still identify you as a pseudonym in a thread. If we were to give everyone "anonymous" as the name, it would be very difficult to identify who is saying what in a group setting.
