Stumbling over this quite a few times, I see people editing very-low-quality questions (most of them OffTopic or DoThatForMe-Stuff with really bad spelling and grammar), to turn them into not-at-the-bottom-of-very-low questions, but still worthy of downvoting/closing.
How do you handle such suggested edits? Should you approve them, or reject and flag the question?
I evaluate the edits on their own merits. There is no reason to leave a question broken in one way just because it is broken in another.
And, of course, flag or down-vote as appropriate.
It seems that one of the concerns is that the bad questions get pushed up the queue when they are edited. I would suggest that that might be a good thing, as those questions come under further scrutiny of the community and that might prompt comments or votes which could help the OP improve.
