You are right, autobuy link from a brand new account might ended up with a non satisfactory product at least the op should know this by him/her self.
I guess the op should be able to provide a vouch copy to a highly trusted member here who can certify that this script actually function.
You know what means to scam people, you did it successfully in the past (this guy is just ... another scammer - check his feedback)
My general advice for all users: do not buy anything without using escrow!
