I didn't care before you and 邋遢道士 posted your opinion. It's totally ridiculous that someone asked Bai to identify himself. However, it's also kind of ridiculous that you and 邋遢道士 asked him not to do so. If Bai wants to expose himeself/herself, that's his/her business. Why do you care? Why would he/she get hurt?
Since both of you are member of "internal forum", the whole thing becomes very interesting now.
