Separate accounts, same user names and notification bugs

Hi,

I have two bitbucket accounts, one for work and one for personal projects;

Work : john@offroadcode.com
Username : John Bear

Home : creative@madebybear.com
Username : J Bear

When I commit code changes to my home account project, I get notifications by email to my work (as if I've committed using my work account).

Somehow, my accounts are 'linked' and I don't want them to be.
