Heya,
I'm actually writing this on behalf of my son who was banned today --- noob!
We both apologize and I will go over the rules again with him. I'm not sure exactly what act was committed (the reason I found was "general griefing"), but if you can specify, I'll reinforce that extra well.
If you're okay with lifting it, I'd suggest keeping him banned for at least a week, so the point is made!
Thanks
