As a CO I have the ability to delete photos in logs. When doing that, I have to give a reason. That's a pretty good feature, even though I think it would be more appropriate if it was applied to deletion of the entire log. Obviously, the message should turn up at the owner of the log, but apparently it doesn't
I had a suspicion that nothing happened, (I didn't get a reply on the last message I sent) so I tried it with a friends account. Yup! No message appeared at my friend!
