Again like Raftaar's case, you were tempbanned not banned. This section is for "bans".
I'm still not buying whatever you are saying Roxas. Brother or no brother I don't care. If both of you were on 2 different machine/computers, you would have had 2 different UIDs but that wasn't the case. Your tempban period will not be reduced and it will stay at 48 hours / 2 days. End of the discussion.
