What's your technical method to prevent users from creating fake accounts?

General Discussion
  • What do I mean for ''fake account''? Some users create different account for different reasons:

    • Trolling
    • Voting!
    • They are very shy: Assume A is a professional user in your forum and now he has an elementary question! A creates another account to ask his simple question.
    • etc
  • NodeBB core doesn't have anything to prevent this. But plugins can be made to prevent multiple accounts from the same IP etc although it can be easily by passed.
