Do multiple submission at social network considered as spam?

[K Z]

I am confused these day and find no clue to answer the question that I work on many different social networks to promote the content of my blog. I came across the website like Ping.fm or add-on like Shareholic to get your content submitted to multiple social media websites in one go.

My question is if I do multiple submission, will it be considered as spam by search engine like Google? will it be harmful for my search engine optimization?
