Possibly critical bug: Commenting to one hero, but all heroes can see it?
I'm not sure if this is a bug or it is intentional (to which I would suggest a change), but when I go to a hero's page as their ally, and leave them a message, the message shows up to all heroes that have me as an ally, and for all they know, that message could be for any of them. I also see all of my ally's messages to their other heroes as well. I think messages toward a specific hero need to be private only to that hero so that there is no confusion.

I have had this too, as an ally I posted on my Hero Friends wall asking their goals for the week - It posted under my Hero name/avatar and also appeared on my own Hero activity wall. I think perhaps some more barriers between being a Hero and an Ally need to be erected if possible to ensure privacy of our friends who may want to restrict info getting out to be only to their own specific circle of allies. Secret identity and all that.
