If i rewrite my article,and use a different main keyword? Not a *whole* rewrite just adding and subtracting some tips and general points.
As you probably know, they got some kinda "article originality" checker....So if it doesn't recognize yours as a duplicate you will be fine.
If you modify it in a big percentage,I heard something like 50-60%, then you will be ok and you will also rank well in SERPS.
