There are only 34 bugs that have recent updates AND were created in 2005 or earlier. Surely something can be done to ensure that these issues get higher weighting in the priority list. At this point, you are unlikely to get more votes on these issues because people now assume that confluence just can't handle anchors properly and avoid them.
Personally, I am now in the habit of hardcoding the link to an anchor. This annoys me to no end because the DNS names of our confluence servers all changed recently. All of my anchor links are broken
The query to find old bugs with recent activity is "project = CONF AND issuetype = Bug AND status in (Open, Reopened) AND created <= 2005-11-25 AND updated > 2009-01-01".
Seriously folks, it's time to get rid of this technical debt.
