PageRank has nothing to do with the "freshness" of you content. It has to do with the quantity and quality of inbound links. It is a measure of link popularity. Period. If you are using "cheap", low quality link building techniques like forum sigs, blog commenting, article submissions, etc. AND slowed down your link building, your PR will fade. The very nature of these types of link building techniques causes their effectiveness to fade over time. So if you rely on low quality links, you have to ALWAYS continue to build them... unlike natural links whose effectiveness does NOT tend to fade over time. For example, when you first submit an article, it likely appears on some Recent Articles page that has a decent PR and backlink profile and provides a decent boost. But once your article rolls off of the Recent Articles page and can only be found deep in the article site's archives, the archive page that links to it likely has very few if any backlinks, so the boost that the backlinks in your article provide to your site diminishes greatly. And if your article didn't get any direct backlinks while it was on the Recent Articles page then it stands a very good chance of eventually getting deindexed. So when you submit articles for back links, build links to your article as well to keep it indexed. Blogging has the same paradigm as posts move off the home page, and eventually off the category page, and is only accessible deep in the archives... Same goes for forum posts...
No doubt PR can drop, and to maintain or to increase it you need to do regular work on building quality backlinks from relevant sites.
Perhaps generally true, but even good natural links come and go. I have seen PR drop on the loss of a single high level cat link in DMOZ. I have seen PR drop when a single linking site was redesigned and that one PR4+ link was lost. I suspect that the end of Geocities is going to have an effect on any number of site that might have been linked to from those pages - good natural links that had been up for many years. My point is that the ebb and flow of PR is not soley dependent on "low quality" links. Good quality links provide insulation, but no guarantees.
PR may be drop, it not mean than your site getting something bad. It totally depends on Google' internal policy. How they improve or decrease any website.
This is a matter of everyday work. Always posting new content (text/photos/videos/sound)+ adding new links (internal in your web and coming from other sites). If you fail one single day, you start to go down. I have got a site with PR6 and went on holidays by 30 days. When I came back it was again 4. It have taken several months to reach again 5
I want to suggest you that first you should remove all spaamy link from your website and send a request from google website then you will get any reponse, because this is my expereince .
page ranks can increase and decrease the reason why page rank decrease is because you are not building more backlinks for it any more may be you think it would get higher by it self
