These are rather out of date though. E.g. it says "Otherwise please use the original title, unless it is misleading or linkbait", which does not really reflect the current policy of "use original title no matter what".
That's quite wrong—we follow that guideline meticulously. All day long we change titles because they're misleading or link bait. Mostly it goes without notice, and that's by design: we try to be unobtrusive.
