in order to update the robots.txt file i found you create a robots.txt file in the shoutcast directory that says
user-agent:*
allow:/
then in the sc_serv file you type in ( robotstxtfile=robots.txt ) then that will update the localhost/robots.txt that your shoutcast server makes
example
code:
www.djcrazyjimmy.com/robots.txt
hope this help anyone who might be looking for the same information in the future.
