What Is Google Saying By Reducing The PR Of Google.co.jp

IS Google trying to show that they are very sincere by reducing the page rank of Google.co.jp. Didn't Google knew this earlier? Or Why did they give this punishment only after it was said by someone else on their blog?

So many Questions pop-up into everyone's mind. First of all I would like to share that Google doesn't worry about anyone whether they buy a link by Paying per post or by Pay Per Click. Since the Crawl is automated in Google, it checks whether the link is having proper value is it related to the content. When these features are satisfied it considers the link as backlink or else it continues.

Google takes the problem in its hand only when it gets complaints from a third party. It just doesn't bring down the page rank as soon as they get a complaint. They register the complaint and there is a team which analyzes on the complaint. When it is proved they go on for the punishment.

So Google doesn't really worry on they type or the measure through which the link is obtained until they are forced to have a look on it.

Now another question may arise, whenever a site goes low by PageRank is it a punishment?Absolutely No! sometimes it happens naturally when some of the old links which gives the PR juice are no longer there or removed the link or some of the PR backlinks are devalued and so on.
