I just deleted your latest post, because it also contained a quite unnecessary link to your website. You can't use our site for SEO. So please don't do that in the future.
That being said, it might very well be right what you said there: PR 0 is an "Over Optimization Penalty". As your profile says (I left that out of my previous post" your company specialises in "SEO services" also, so you're the expert here.
But I don't think it's very smart to continue doing it in the post I deleted. Aren't you glad I did?
