Please be aware, that the cloak detection is still experimental. A minor change must not always
mean that there has been a serious attempt to trick the search engine into indexing something more favorable.
Sometimes a minor change of the returned header can simply mean that a different server has been returning
the request. A minor change of the content can be related to the use of a content optimizing software.
Though these changes are not considered "good", they do not necessarily result in serious punishment.
