Password Protection: An Idea on Fake Patron Protection (Patreon)

I have an idea to further deter fake patrons, and I want your opinion on whether to carry it out or not.

All files regarding Unbreakable Bond will be in a .zip file. The zip WILL be password protected, and I had been thinking of sharing this information directly in the post itself. I planned this to block access to those who somehow obtain the files from somewhere else.

My new idea is that I share the password information NOT publicly, but privately, by individually notifying all my patrons - those that I'm sure they're then charged. This may mean that you might truly obtain your pledge reward days if not a week after pledging - whenever I decide to charge my patrons. It might also mean that I will increase my charge routine more than three times a month to get the stuff faster to my patrons.

If I decide to do things that way, people who have been pledging before the release of Unbreakable Bond obviously won't be affected by any delays, as I will charge and then share passwords immediately.

What do you think? Is it a good idea? Or bad, due to how easy it is to share one single word? I await your thoughts on the matter.
