Okay, I was actually responding to your "but these are virtually non-existent since peer review/editing is time and labor intensive", but I suppose you were referring to the process of finding peer reviewers.
I actually got sent my first outright awful paper recently, and there wasn’t in the end much of an onus on me. The flaws of the paper were so blatant that I could simply tell the editor that the entire premise was unsound without having to go into much detail, and the editor understood.
