I remember before he was asking how to delete his account, I think someone was after him.
So you think there is a connection on why he tried to change/edit all of his posts to "0", you got an awesome theory but I doubt deleting his account would solve anything if someone was already after him because he didn't even clean his account entirely all the zeroes end after the 62nd post. I got a feeling that he just changed his post to 0 because he is trying to clean his account from all the posts where he gained enemies with along the way. He might just be trying to reclaim some respect by doing this but what he is doing now will be viewed negatively and will just damage his reputation more.
