Questions:

1. Who is responsible for adding guardrails to ensure all papers coming in are thoroughly checked & reviewed?

2. Who review these papers? Shouldn’t they own responsibility for accuracy?

3. How are we going to ensure this is not repeated by others?

reviewers are unpaid. its also quite common to farm out the actual review work to grad students, postdocs and the like. if you're suggesting adding liability, then you're just undermining the small amount of review that already takes place.
