Message if user blocked

If I block logged-in user on master site, I will have message about that the current user is blocked, on each page. (Bakery will attempt a login on every page, because we have identification cookie). It is not obvious to the user, because he didn't try manualy login on current site.

How to reproduce:

We have 2 site - "A" - master site. "B" - slave site.

1. Log in on site "B"
2. Block this user at master site "A"
3. Goto site - "A"

On each page we have message: “The username name has not been activated or is blocked.”

Note: Site B - the website on Moodle
