"On my message wall I can delete his posts."

But it would still come up that he had posted anywhere

I DELETED HIS MESSAGES

It does not work that way

Ok then how does it work?

You can delete messages off your wall, but even if that was his only post, it would still say he has 1 post

He had 3 posts and I deleted them off my wall

If you were telling the truth it would say he has three posts

How? I deleted them and he was blocked

Im not lying look:

He did that 3 times
