Only site administrators and moderators can see what you post privately and know about you. We don't share that though, and have no intention of ever using it against you in any way, shape, or form. Simply put, if you don't want us knowing about things, don't post them. Better yet, set an encryption phrase in your profile and we won't see them at all!
There is currently no support for "right to be forgotten", but we'll get to that.
