Page rank is migrated

The page rank on imknight.net is moving to imknight.net slowly, but quite disappointed that imknight.net is only on page rank 2, this is falling from page rank 5 , 3 level high.

Although i know that google is punished those selling link blog, but so far i never have these thing on my blog , although i did register the TLA service, but so far no one bought my link before, i really doubt that is this page rank drop related to this ?

lets see how long it takes for me to climb back page 5 again. This is not the first time,  It happen to me long long time ago .
