Thank you for the update and for allowing us to see the logs, it will be interesting when looking for possible patterns and being able to track the forum.
You should thank the karma abuser, he provoked this change. This is already the second change or new forum rule on the forum for which he is responsible 
To be fair, Presidents have previously had access to karma logs, but it was never regular and only when requested or dumped upon, so wouldn't call it a new rule per say. But having a weekly or monthly log is certainly an improvement.
Per your other point above, I otherwise think certainly best to keep away from mods, no offence to any of them, only we've had bad apples before (N***man) and it would definitely be very easy to abuse such data (I'm thinking mainly retaliation against -k). Global mods would also be fine as a trusted group who have all been around for time so could be posted into that section otherwise. Probably useful also for some of the bigger local language GMs.
I am surprised that the admin was too patient in handling that guy. This is not the first thing he did, which is frowned upon. Even the admin talked to him multiple times and warned him not to continue, but sometimes people want to prove themselves. I am happy to see the case closed nicely, as expected.
If you haven't noticed yet, admin is a complete soft touch. It took years before he agreed to even allow global mods to block users from posting. This is certainly not a bad thing even if it has been frustrating in the past. There are plenty of users who change their behaviour with some encouragement, even if most don't. I've always admired his efforts to give users an out, even when it has been a waste of time, or completely backfired. (I'm thinking N****man yet again, he had way too many chances and abused them all).
Freemind rules with an iron fist by comparison
(mod in joke). On this note, our President should probably have access to 3 strikes, plaga penalty, and spammer groups by now wouldn't you say admin? VP and the rest of us have it, and I think he can be trusted by now
