Please note that there is a separate thread to report griefing incidents: Have you been griefed?
As hard as we try to be available on the server whenever we can, there are some times when an admin isn't always available to deal with every issue. In this case, please use this thread to report any rule-breaking that you feel needs to be actioned.
One of the most important things to do when reporting an incident (besides telling us who's doing what) is to take a screenshot and include it in your message. This gives us proof that they were doing what you say they were doing. For example, someone spamming or swearing in the chat can be more quickly banned if you send us a screenshot so we can see what they were doing. Everything is logged, but those logs aren't always immediately accessible.
Information on taking screenshots in Minecraft can be found here. You can upload the screenshot to a website like imgur.com and provide the "Direct Link" in your post here.
