"I'm sure everyone at some day or stage of their life have been confronted with these words, however meaningful or meaningless they may be to you. Just as we have all in some type or form experienced BULLYING," Cameron wrote.
"To whether you were the bully, the one that was getting bullied, a bystander or even known a loved one that has been bullied, we have all been confronted with the very REAL impact it can have on an individual!
""Sticks and stones might break my bones, but words can never hurt me". There was one time where I believe this to be true, but truthfully words hurt and can and have shown to be able to kill as well."
Cameron goes on to highlight the difficulties and pressures the players face each week as professional footballers, referring to "the tireless work off field, the extra gym sessions, the dieting, the injuries, the rehab," which she has witnessed first-hand.
"I have seen the good and the bad that comes with having a brother who plays in the NRL," Cameron added. "I feel angry, sad, heartbroken, irritated, helpless and useless as I sit here and read the hurtful and hateful comments targeted at a loved one. I truly hope you never have to feel this way about someone you love, as everything they stand for gets questioned and criticised."
Cameron finished with a plea for fans and would-be trolls to, "Please think before you post something negative online. You have no idea how many lives you can be affecting with a single negative comment," and signed off with "Yours truly, A concerned sister, mother and fan."
