Not exactly true- if you put it in a publicly open location, yes.
FB ( and other such sites ) allow you to make things private from the general public. The people who don't do so & put up such things as where they went to school, their current job, past jobs, etc. with their legal name, are opening the door to potential trouble.
It's a patent falsehood that ANYTHING outside secure classified government networks is private. Believe me, I've been in the position to know.
The crossdressing community is one that needs to stick together and continue to be there for each other for whatever one needs. We are always trying to improve the forum to better serve the crossdresser in all of us.
