High Google PageRank Domain Fraud: "the bad guys know you are thinking this and they take advantage of a "loophole" in the system that isn't known to most SEOs.
The Google Toolbar. Google really didn't know what they were starting when they first introduced it back in 2002. Now, millions of webmasters all have "Green Bar Addiction" and they watch their PageRank values as closely they do the stock market.
The Loophole: In order to protect their algorithm from their competition (Yahoo!,Microsoft and "black hat" marketers), they publicly show "delayed" PageRank. Much like the free stock quoting tools online are 15 minute delayed, the Google Toolbar is delayed too. Only, it isn't just a few minutes, but 3-5 months!!"
