I would not normally ask questions about PR, however curiosity has gotten the better of me.
I just noticed that the PR of a previous PR3/4 site has gone to 0. Everywhere I can check it shows it at 0. Fluctuations are normal, but it shows 0 on ever datacentre and crucially, DP shows it as being 0 since September. It has healthy backlinks and I am at a loss to explain why it has dropped. Most predictor tools show it it will not increase.
It is not banned, most of the traffic comes from Google and the site runs Adsense.
