wever, when I did this last year with real people: majority wanted to take advantage of me, use it against me, laughed at me, and even abandoned me.
Sadly, the world can be like that.
But, like digger says, if you keep your forum name to this forum only, don't use a photograph of yourself or family pet etc,then it is unlikely that anyone who doesn't already know what your trauma history is, would recognise you.
Other things that I don't talk about are, my job, what area of the country I'm in (or was in when trauma happened) or those sort of unnecessary details that could identify me. I also use a different browser for this site than I do for others, and I don't have it kept on a favourites tab. If anyone is coming round who might want to use my PC, I clear the history on it too.
I might be wrong in saying, but I thought people here were allowed one name change or something? And if it was possible to change your user name, it is worth changing it to something that is very common - Meadowsweet is a plant, and when you google it, you get lots of information about the plant and nothing about it as a username.
But beyond all the precautions that you can take, perhaps this is also an opportunity to assess what risks are real, and what aren't, as well as what risks you are willing to take, or not. For example, there are people who could pose a risk to me if they felt that I might go to the police. But I am only in danger if they know where I live. So I wouldn't talk about it here if I decided to report it, and there is nothing here that they could find me from.
In terms of my family and work colleagues, I would be devestated if they knew the details that I share here, some might even reject me or get angry with me. I've weighed up that risk, and although it could be extremely upsetting, it wouldn't put my safety in danger. So although I take precautions to keep what I write here private, it is a risk that I am willing to take in order to gain what I do from the site.
