Is Inlinks Companies Like Kontera ANd infolink Destorying Our Pr?

Hi
I want to know ur comments about it .
If im not wrong actually the inlinks advertising companies like kontera and infolinks are destroying our pr and effecting google search
Bcoz they are targeting keywords in the site and hyperlink to advertiser site.
So if im not wrong they are getting external links from publisher sites and giving benefit to advertiser and harming to publisher’s site.
IM not sure whether im right or wrong But i want u to comment on it
Also any personnel from these companies can throw a light on it.

Thanks
