Simple request:
Currently the default ban time is 0 which is a permanent ban as you know.
I Run multiple servers using ulx but i always find my admins accidentally permanently banning people, they say they are in a rush to do it and they put extra spaces in when trying to type it in. I Suggest 600 which i currently have modified the code to, but every update this is one thing i do not remember. It would be ok apart from they don't want to remove that person because they deserve a ban and don't bother changing it by removing it and using addid.
A better solution would be, the admin that created the ban could edit his own ban (I don't have female admins, do you?)
