It's possible, but not probable. You could PM the author and politely request that they send you a script as a prelude to possibly purchasing it or you could ask someone in general about a certain file.

It may be wise to install some mental defenses in your sub before giving them anything you don't trust, or anything not explicitly from YOU. (Mental defenses would be good in any case, regardless of if you're the master or sub in the relationship if you yourself use files or other hypnosis services.)
