A temp_ban only lasts for 1 hour. Now, if he got a perma_ban, then we'd need to hear from the Staff Member that banned.
Update us to let us know if it was only a temporary ban.
edit:
looks like Brian posted just before me.
JR, have a talk with your brother. Once you agree to what Brian has stated (no more spawn camping), then I'll lift the ban later today when I get home.
