I thought this was quite a good reply on her Insta page.
Basically saying that irrespective of who had access, she holds the ultimate responsibility for the security of that account and the actions of its users.
"Without being rude, if many people have access to your Instagram account then that's your own fault. You shouldn't be so lax with your account security. Perhaps you can work out who knows your details, or has access, and then work on clearing your name in terms of selling stories... but you still have to take responsibility for it happening in the first place, as it's your job to ensure that your account is used only by yourself.
You can't call Colleen out for this, and seek legal advice on her naming you, when it's her privacy that has been invaded because of you/your account.
Sorry you're pregnant, must be really difficult to deal with carrying a baby and having a bit of drama in your life... But I imagine all those people who are going through cancer/other illnesses without being able to afford holidays, or a less than basic living condition have it worse. Chin up, you'll soon be a mum, and you will still live a good life. This will pass, and your life will continue. Be grateful."
