I was asked to check a proposed edit of a question. I rejected the edit, saying "The original question makes no sense but is at least grammatical. The proposed edit is ungrammatical and still makes no sense. I understand neither and so will not attempt an improved edit." (Actually, a terse version of this to respect the character-count limit.) When I returned this, I received a reply telling me that the proposed edit had been accepted, but inviting me to edit the post directly.
This is not the first such experience. If it happens again, I will be inclined to ignore further requests to check editing. I think it a shame, though, if the system discourages good editors and encourages bad ones.
Edit: Well, a similar thing did happen again, with the same robotic message popping back immediately. Sadly, I now think that there are better uses of my time than responding to invitations to edit questions on this site.
