Unspoken prayer request: another Christianity confusion

On my Facebook news feed, a post popped up from a person in a "KJV (un)Believer" group with an "unspoken prayer request". 

And I thought: seeing he spoke about it, the prayer request is not unspoken. It only isn't specific.

In that respect:
1) God is not the author of confusion,
2) God will not hear vanity,
3) God heareth not sinners, and
4) I'm to pray with the understanding. 

So, before asking for specifics, I first asked for a testimony.

And this stuff seems quite prevalent. 

On Twitter, I saw many persons tweet an unspoken prayer request. One had the side note that God knew all about it. In that case however, what is there left to pray about? 

Nothing.
