Comment 2 for bug 53637

Today we had an example of how the lack of confirmation between team membership subscription could cause much annoyance.

The ubuntu-audio team added ubuntu-kernel-team as one of its members. Someone from the ubuntu-audio team subscribed it as a support contact for launchpad. Every support request filed against launchpad was also spammed to the ubuntu-kernel-team members.
Members of ubuntu-kernel-team couldn't unsubscribe ubuntu-audio from being a support contact for launchpad. (bug 68732)
