My own feeling is that for questions where the problem turned out to be a simple typo, and from which this could not be discerned from the question itself, should just be deleted outright, as they offer no value to anyone.
By contrast questions should be keptquestions should be kept even if it was a simple typo, if this was present in the question, as the question is answerable and will be of use to others.
In this case, according to the user's comment, the problem was not with his sudoers configuration, which he asked about, but with the script being run, which wasn't provided. There was no way for anyone to know this by reading the question, and no way for anyone to arrive at the answer.
