If a mod is not active enough, I would first check to see which mods are responsible that area, and *politely* PM all of them at the same time for help (put semicolon between usernames in PM "to" line). If that doesn't get any results after a few days, contact a couple of admins and politely ask for help.

. When you report the post using that functionality, staff gets notified, and it goes into a work queue.
