I really like this script! The only thing i really didnt like and which could be easily improved is, that you can also ban offline players.
The simple way of changing this would be making the command be like this:
command: /b [<offline player>]
command: /b [<player>]
Then you can ban offline and online players thorugh the script!
Other wise I cant complain about this! the banning works great and so does the freeze script built into it!
Thanks a ton for sharing!
