building backlink

Hello guys, below links are kinda sites I build my backlinks, (Powered by phpBB) Sites, most of them are relevant to my blog niche while some are not, but I think I kinda need some advice about the sites, I don't want Google to penalize me for doing anything wrong...

Hi all how i can rank my post pages. i know i have to build the backlinks for each page . so how about buying cheap backlinks ?? what are your opinions ?

I'm looking for someone to build me Quality, Contextual, backlinks from .ca domains, PBNs and Web 2.0s as long as they are high DA,PA,TF and CF in a relative or general niche. I need 1000s of them slowly over time. I need full reports.
