I see that happening at least once a day so I'm bringing it up.
A user, most likely new to SO, asks a question that is not interesting or that doesn't make a lot of sense or it's not a real question.
At that point this question gets downvoted two or three times and gets closed which seems normal.
Then someone goes in there and edit the question so much that it's not really the same question anymore... or at least it has nothing to do with what the original user posted in term of phrasing.
Now people viewing this question will go "oh, it doesn't deserve -3, it's an ok question" and the question gets upvoted until it gets at 0 or 1. Maybe more.
I think it's good that a question gets a "second chance" to be answered, but I'm asking that: in the process the user got some reputation for asking a bad question (because downvote value != upvote value).
The idea case would be the downvoters going back and cancelling their votes, but this doesn't happen often. So shouldn't a entry closed, edited and then reopened be set as community wiki by default, or prevent the user to get rep for it (if it's not already the case)?

It got edited and it's now pretty interesting and should be re-opened shortly. The user already got an upvote on his question and got rep out of it.
