By default, every broken build displayed on the Build Monitor is accompanied by a "list of possible culprits". This list is a list of people whose commits might have contributed to a broken build.
The purpose of displaying this information is to provide a point of contact to whoever has touched the broken build last and should (hopefully) be able to fix it the quickest :-)
However, if you'd rather not have this list displayed - you can disable it in the settings.
