Experts Coloumn Delete My Article

This is the forth time I had my article deleted on Experts Coloumn. My first and second article was deleted because I put link on body, then I realize that based on writing guidelines this is forbidden. then my third case, it is because the guidlines could not accept my topic about health se*x tips ( about healthy concern ) and the forth one was deleted because they find it copying from other site -well, I write it by myself, I re-write from Indonesian article then rewrite with editing in English. the funny thing is when I re-publish the last two article on Triond, it's successfully publish without problem. Do you think Experts Coloumn writing guideliness too strict?? anyone experience the same thing??
