Spun articles in same article directory?

Been spinning some articles, and I just wonder if I will get my articles approved even if read by an actual human, they can tell that they are almost identical.

One other thing, how many spins can I get on a single article to still get a unique one (without the articles becoming too much alike).

Using a program that could make 10k spins of a single article, and I really dont believe that I can get 10k UNIQUE articles from a single 500 word article...

aww crap, I posted it twice.. sorr bout that, my computer froze up, so I figured nothing happened the first time.. can a mod delete one of the two?
