Article sites backlinking question

Hello guys,

I'm an old lurker of the forum and have returned to try a few out a few things (unfortunately I forgot my old user ).

Well, what I wanted to ask, if I want to post to multiple article sites for backlinking purposes, do I need a spinned article for each one of them? Is it really necessary or can I use the same one? Do you know what difference it would make spinning each one of these, given that they are only there to feed the backlinks?

Thanks!

After panda, it's advised to use spun content.

The articles need to be spun yes. If G see's the exact same article on multiple sites all pointing to the same webpage, it looks pretty obvious what you're trying to do.
