This is for if you don't think your admins are doing a very good job. Go on your server on a different profile (a friends) and test them with this. 1. "I'm from planet minecraft and I would like to review your server by flying around!" If they fall for this just fire them now. 2. "Who's the owner? Is he cool?" 3. "You are a bad op/admin" 4. "Can you give me diamonds/op?" 5. "What plugins do you have?" See what happens and then you can tell if you have a good or bad admin. Post in the comments (if you want) how your admin answered these questions.
