[block Character creations that uses unauthorized names]

so I have this script for unauthorized names that log in,

-	script	UnauthorizedName	-1,{
    OnPCLoginEvent:
		if (!getgmlevel())
		{
			if(compare(strcharinfo(0),"GM") || compare(strcharinfo(0), "Admin"))
			{
				mes "^ff0000[ System ]^000000";
				mes "Illegal character name Detected.";
				mes "Character will be deleted";
				query_sql "DELETE FROM `char` WHERE `name` = '"+strcharinfo(0)+"'";
				sleep2 3000;
				atcommand "@kick " +strcharinfo(0);
			}
		}
        end;
}

 

What I want to know is, How do I block Character creations that uses unauthorized names?

Is it even possible ?

 

 

 

  in advance
