Hey, firstly this is the wrong section
I would usually be around at that time but was out for a mates birthday. It's totally untrue that there is 'nothin you can do'. You can spectate, get a demo showing people breaking rules then post it on the forums. This is a habit you need to get into, should your admin application be successful. But really as a community member it should be done anyway!
As a server admin, especially in early days, you can't just press the ban button without proper evidence. I know it's not the most fun thing ever and that you would rather play than sit and demo someone, but that's something that comes with the responsibility of being a community member/admin.
All the best
