Hello
What do you mean about spam? Link spam?
Which type of link spam?
Blog comment? Articles? blogs?
What will do the google? They start punish the sites which have got too much links? In this situation will start the negative seo.
everibody can kill other peoples sites.
My opinion. If you use longer article, which are longer a little bit. (Not just 100 words) from varius channels, there will be no problem.
