I used to worry a lot about my T identifying me but I think if she did spot a post and suspect it's written by me I suspect she would stop reading immediately. In the UK it could be considered an ethical breach of some kind especially as it would give her information about me that didn't come from source. It's my right to post here and obviously her right to read what she wants, but when it comes to knowing more about me than she should, I think my rights to confidentiality would come into play. So I try not to worry about it.
