Well not entirely, for pure example say a wiki account tries to register named Velax since it has to be the forum name or the family name I message him on the forums asking if it's him, he verifies then I approve the account that entire process will take more than likely less than 24 hours.
At most I e-mail him in which case it could be handled slightly above 24 hours.
It's not like account making is the Mexico/US border I wouldn't expect it to be that busy.
