I have a question regarding article acceptance on ezinearticles.com.
Is it okay if i copy an article word by word(full and same article is what i mean here) from my site and submit it to ezine?
Do they cross-check with copyscape or something similar for plagiarism?
I recently submitted my first article there which was copied from my site and the link was indexed too. After about 12 days, it got accepted and listed at Ezine today.
Can i similarly submit all such articles which have already been posted on my site?

I understand that these pages on ezine may not get indexed but if they do, i get a backlink and ofcourse some direct traffic from ezine too.
