Assuming they're using Reader, they can't remove scripts from the file.
You can, however, make smarter scripts that only update the value of a
field if it's empty.
Thank you for the reply.
They are all using Pro as well. I will change the script to only update if it is empty. Good call!
In that case you can remove the code, or replace it with a "blank" code...
With the Professional version one can use the Optimize feature to remove scripts.
