[Hacktoberfest Backend] Anonymize Student Names

[bqle]

Some students want to hide their names until they actually jump on the call! Spooky! 🎃 Can you allow students the option to hide their names for a question? You only have to touch some backend files (no frontend needed). As an extension, can you make this an option on a user level? So a student can set their profile to anonymize every question for every class.
