Surprisingly, when I checked my sites' PR rating using an online tool, one of my 2 websites has a PR5 on it’s index. The site is about teh online games i play. It doesn't have any valuable contents (just a lot of articles about my accounts and the games I play). I didn't so any submissions on any directories. How do you think this happened? I would gladly have the same PR rating on my other (more important) site whose PR rating is 1. T_T. lol.
You've obviously piscked up a few high PR links. PR is transferred through links, it's not allocated based on the quality of your content.
