Here is a link to very very sad page - Dead review requests:https://bugzilla.redhat.com/buglist.cgi?cmdtype=dorem&remaction=run&namedcmd=Dead%20Review%20requests&sharer_id=184522
Actually, most of these tickets were closed with improper reason (some should be marked as DUPLICATE, others, marked as NOTABUG should be marked as CANTFIX/WONTFIX of DEFERRED instead) and I'll ty to check and fix at least some part of them. If time permits, of course.
BTW, those people. who using Bugzilla, should check this page, sometimes:https://bugzilla.redhat.com/userprefs.cgi?tab=saved-searches
Some people share Bugzilla's saved searches there, and some of these queries may be interesting for you.
