Even if you look at the handled reports over the last 90 days, only a few people have more than 10 reports.
Report bad posts even if you perceive that nothing is being done, as report stats are one of the primary methods I use to look at how moderation is going in a section, and to assess potential new moderators. Pay attention to your report accuracy; I see a lot of reports marked bad in the French sections. (If you think that a report is incorrectly marked bad, complain about that to your local moderator or in Meta.)
My own reports aren't unhandled, they are rejected.. one of them was for a scam project, with about 5/6 false newbie accounts spaming with google translate to up the thread. Nothing done.
