I was a closet drinker and now I'm a closet AAer. My past is nobody's business, and this is a medium for many to feel safe discussing their various situations without really facing anyone.
Some are okay with it, some are not. For those that are not, we to the best of ability help them maintain their anonymity, it's a matter of choice.
You said in an earlier post you had a child, would you want him to read what you've already shared, seeing your picture attached? Sorta, like that.
