Google Page Rank Up to 4?

Well, well, well... After weeks after I got dropped to 3 for Google Page Rank. It seems to be I might be going up to 4 again. I got penalized last time maybe because there is a Payperpost tag on every post and it might be mistaken as a paid post. I took it out since then and didn't write for Payperpost for quite a while. Thanks Google for ranking me up to 4 again.
