XF 2.0 User with nick of zero characters (possible bug?)

Hi, we´ve had some problems with security measures. We´ve had a user that´s been able to use a nick with 0 characters, change the nick on his own, I´ve also deactivated his account but he´s activated it back again... I´ve erased his account and he´s created another account again with no characters in the nick... He´s been doing that until I´ve shut down the option of allowing new users to create accounts. The system is configured to request a nick of 3 characters minimum, so I don´t understand how he can create a User with a nick that has no characters or has changed his own nick without having the "nick change" option active.

My configuration ACP -> Setup -> Options ->User registration:
  • User name length limit: 3 - 16 Characters
Add-ons instaled:
  • DragonByte Security 4.0.0
  • s9e Media Sites 1.0.12
  • [8WR] Member Utilities 2.0.0.3 (uninstall the addon after what happened )

The add-on [8WR] Member Utilities 2.0.0.3 for xenforo 2, allowed the nick change to users. The problem persists after uninstalling the add-on.
