This answer clearly wasn't golfed, but is still a valid solution to the problem. How should we handle such answers? Should we down-vote them for being long? Should a mod delete them for being off-topic?
At link you've provided, I don't see any word about GOLF.
But if question had such tag or task with words "... the shortest solution ...", then... anyway such ansers will not have any points and after some time they will be pushed to 2nd page by better answers.
By the way, if questioner surely didn't want answerers to golf, maybe we need some tag for this or some note at FAQ or... I don't know any suitable way to make people see it, but somtimes questions at SO didn't suppose to be golfed, but ONE man started to golf and plenty of others continued it.
A solution that was un-golfed in that it was readable. I'd probably leave alone (no vote either way)
There were, however, a few examples on SO of people who evidently tried to write very long answers (which I consider different from my using heavily golfed fortran 77 from time to time). I'd be tempted to vote those down.
