WHERE HAS ALL THE COMMENTS ON USERS WALLS GONE?

I am trying to look through users wall that I have messaged asking questions about language learning and upon finding their account there walls are completly blank? as if nothing has been written or some kind of privacy setting has been activated?

ANY ADVISE?

There were open messages and private messages on the walls. The walls now don’t allow us to choose between such distinctions, so all the past messages have to be erased. This is my guess.

This is so annoying trying to have a conversation with another user.

It seems that you can neither edit nor delete what you wrote on the wall.

Or, every message is treated as secret even from its writer.

Deleting your own posts is possible.
