That's just where the trouble starts actually. If only because information about a person is not exactly contained within the physical person, it is contained in its enviroment as well. This is especially true when you think of spells as True Strike. Heck, even the person that is being divined might not even have thought of his next combat maneuvers, and he might never will (because he is hardly the only factor in deciding where he is going to be on the moment true strike goes off).
So if I am understanding you, it is not okay to Scry the person in the present with Arcane Eye, but it is ok to effectively Scry the person in the future with True Strike.

People won't see the person's friends, or even the enviroment if the Mind Blanked person is being scried, because when we see friends shaking hands with something 'invisible', or answering questions that we don't hear asked, we are divining information about that person. Can we not see his reflection on the mirror nearby, not hear what words he utters to the scrying sensor, but do we see orcs suddenly grow gaping wounds when an unnoticed assailant cuts through them? Is only 'some' information not gathered?
The answer to that is quite clearly written in Mind Blank itself.
The protected character is not viewed, but obviously this does not stop the results of his actions and the rest of the physical environment around him from being viewed.
"In the case of scrying that scans an area the creature is in, such as arcane eye, the spell works but the creature simply isn’t detected."
Again, this focus on "information gathered" screws with people's heads. The simple view of "it does not divine him directly, or divinations do not work with regard to the target and ONLY the target" makes more sense.
People are really focusing on the phrase "information gathered" as it is the key aspect of the spell. It isn't. What is key is that the Enhancement School of Magic and the Divination School of Magic are stopped with the sole exception that Divination spells that gain their information from elsewhere are not stopped.
If I use my Telepathic Bond to talk to Fred about Mind Blanked Barney, that is ok. I just cannot use my Telepathic Bond to talk to or from Mind Blanked Barney.

Do powers from the other planes not answer when asked about a historical events that our currently Mind Blanked person participated in, however indirectly, because they might reveal information about the Mind Blanked person, when the wizard uses Contact Other Plane? If they do not answer questions about the 'assassination of King Osric', do they not imply that our Mind Blanked person is involved and thereby still allow you to gather information about him through this divination spell.
Clearly, such a broad interpretation leads to utter nonsense, when truly applied as you say it must. Information gathering is too broad a term, even when only applied to all divination spells.
I agree here.
If you get the information from a different source (and that source does not use divinatino to get the information from the protected creature), then the divination works because it is not targeting the protected character.
But, you cannot get a bonus to hit against the protected target via a divination spell. You cannot read his mind. You cannot have him telepathically communicate with you. You cannot scry him. You cannot use Tongues against the protected target because the targeting of Tongues is a single creature.
If the divination spell explicitly states that it gains it's information from a different source (outsider, deity, etc.), then you are not getting the information from the target.
Granted, there may be some gray area spells, but True Strike, Moment of Prescience, Foresight, True Seeing, See Invisibility, and Tongues are not among them. You cannot get information from a character that is effectively invisible to direct divination spells and all of these spells must be able to target the protected creature in order to get information about him. They do not target his environment to get the information.
Divination itself can be used because it gets information from a deity, however, even spells like Divination can be thwarted depending on how they are used. If the deity has to get the information through the Mind Blank (e.g. What is the creature doing right now?, presumably an "activity" Divination could normally handle), it fails. Granted, a deity could get around this by sending a spy, but that seems to defeat the DND intent of defense trumps offense.
