Same thing happened to me, and I don't use either a HUD or Jurojin. So I have no idea exactly why it was locked, fortunately now is unlocked. For the last couple of weeks I used this https://freedom.to/ a software that blocks apps that distracted me while playing. In the past I also had my account locked when I used to record my session with OBS Studio. My guess is that their security system automatically detects any software that's not controlled by the user as AI/bot. So maybe you should try not to use Jurojin.
