Two suggestions (suggested in Demolition so copy and paste, no hate please!)
First of all, I think it would be a great idea to list offenses and ban information. Like this:
1. The use of any programs/scripts [cheats] -
ban permanently2. Advertising other servers -
ban for 7 days3. Offending players and admins -
ban from 30 minutes up to 3 days4. Use of any bugs of the maps / server -
ban for 1 day5. Impersonate another person or admin -
ban for 7 days6. Long time camping -
kick / ban for 2 hours7. Other offenses -
admins considerationPunishments of course can be changed by the appropriate high staff members or head admins of the servers. You can add more offenses and their punishment information as well but those are pretty much the basic one's.
Also I would love to see each head admin making something like a journal of their server. In that journal they would list all the things that are done regarding their own server. Let's say:
21.05.13 -
Player1 is selected as new DEATHMATCH Head Admin.22.05.13 -
Time of the map has been changed22.05.13 -
Three new admins selected for trial - Player2 / Player3 / Player4and so on..
Opinions and comments are welcome!

If there is something that you're unclear of, ask! I'll be more than happy to answer them instead of leaving you clueless!
