I agree with your criticisms of the grammar, style, and proofreading in the abstract. In practice, you could state this a little more nicely when it's obvious that the author isn't a native English speaker (most likely a Slavic language in this case) and is doing his or her best to work in English instead of accusing them of being sloppy / careless.:)
