I'd report (1) as broken English, and (2) as plagiarism.
(2) will be good but IMO the (1) should be accepted nicely, I was once using tranlations back then whenever I talk ti my Chinese Co-Worker, never know that it was a bad grammar but he do understand it, so I think we should be the same.
Unless they're doing it for a long time and does n't still learn anythjng and just keep on relying to those applications...
What factors have you considered justifying that his thread was automated and never been his own translation??
Yeah, Upon reading the statements it must have been translated by his own (I mean without using translator apps)
