Whilst you record a hacker, do add a notice to that player so it becomes a bit easy for us to track him down.
For example if you record a person named John_Doe_ (example), when we go to the database, so many other john does appear and the one guilty becomes harder to find. So if you guys take some time to add a notice !notice <player> <reason> It will become easy to find that person and he'll be busted much more quickly.
And while posting their ban request, paste the image notice (Open the players profle you noticed, click the notice ban ID and copy the image) if you can, to make it more easy.
Hope you guys read this and follow it for much more ease
