Can I lose my rank?

Yes admins lose their ranks all the time for doing the wrong things. It is very tempting for an admin to abuse their powers – DON’T. 

You may not even be warned before demtion because we hope for great things from you (not the opposite). If you are an admin you are expected to be a VERY GOOD example to others. If people see you or other admins doing the wrong thing on the server then they think it’s ok and it’s not ok. So admins will lose their ranks very fast if they break the rules.
