This script is fake.
It doesn't have anything to do with neopets but facebook.

There is a cookie grabber in it

This is a broken copy of my script.

There are evidences that a cookie grabber will be added to the source code soon.

This is a COOKIE GRABBER!
Do NOT install it at all.

In the code, "autobuy_version" is actually your pin number, "autobuy_id" is your password, "autobuy_method" is your NP in bank, "Place" is your username

Well, I haven't tested the script. But the code tells me more than testing it.
This script has potential. I like scripts that interacts with external tools.
