How hard is it to understand?

I don't understand some people. I am an ex member of a poem site called PoemHunter and I plainly said on my profile that I'm no longer returning to that site. I even gave links where my fans could find me, I gave my DA (deviantart) and my facebook link, but why oh why do people keep messaging me on Poemhunter? I check the site once in a blue moon since it still contains my poems (which I also have on DA) to see what's changed. I am still reciving messages from these guys from other countries (they know english) trying to talk to me... and I personally messaged them back telling them I am no longer a frequent member. One guy checked my links out but still he continues to try and message me on PH. DA isn't that scary is it? Am I that hard to find on Facebook? Why don't people listen?! How clearer can I get? I am no longer returning to Poemhunter! Once in a blue moon but no more! *sighs* people are confusing to understand concerning simple logic.
