Assuming you are referring to non-books kind of content: I assume that if this happens to anyone, we'd learn about it and all stop seeding AA's content until they explain what happened and how they're making sure it doesn't happen again. The poor person this happened to will have to explain that this wasn't at all what they thought the software was doing.

As I said in other comments - yes, this requires some kind of trust in the AA project. Personally, I tend to have more trust in this kind of projects than in big corporations, of which people are happily running their binaries without blinking. However, I'm not trying to convince people to trust AA - this project is simply meant for those who want support them.

AA has plenty of illegal and gray content. It's not something laypeople should help to seed. You need to go in eyes wide open and protect yourself if you're participating, which I do not feel you are sufficiently emphasizing in this pitch.
