How would peer reviewing in a user repo be more a sense of false security compared to official repos? I don’t know any of the arch maintainers, so for me it’s also pure trust they don’t do shady stuff.

Peer reviewing would not be failproof for sure, but at least it would give more security than not reviewing the pkbuilds, and especially to those that aren’t too familiar with them

I would argue that it’s their own fault then. Laziness is not a valid excuse to put yourself so much at risk. If you start doing it consistently, it becomes a habit and won’t take much effort. Of course, the familiarity with PKBUILD syntax has a learning curve

But a peer-reviewing system would be a better approach in AUR. Weird that it’s not been implemented yet.

I don’t get all the noise around AUR being unsafe. Just verify the PKGBUILDS whenever you install or update something.
