Is it allowed that Judge state: "From this point forward you and any of your family is hereby banned..."?
Sometimes having a disliked family name sucks.
I remember in Oritolon realm on Colonies, there is an infamous Jeckyl family name who has "his whole family hereby banned from entering the realm..." thing but he was not banned due to his escape with all gold
His story: His character Doctor was a Banker who set the lowest tax rate for every realm nobles and absconded with lot of ill gotten gold possible, causing the whole realm to collapse with no tax gold income. We were using the old system at that time where Banker was all-powerful. You can say "you ban the whole family if they come back" due to their family infamous character who took all the realm gold yes. There has to be IC reason for it, such as their last character caused the realm a lot of damages, and so on.
