The last theymos checked within the french local board there were only 6 reporters within the last 90 days, and these were very low reports counts too. Whether, that's improved or not I don't know.
There aren't enough reports there. Here are the top reporters over the last 90 days, unhandled reports only:
+-------+-----------+----------------+
| count | ID | reporter |
+-------+-----------+----------------+
| 9 | 1056600 | baba0000000000 |
| 7 | 1007192 | JeremyB |
| 7 | 1082600 | kenzawak |
| 3 | 1456247 | eklA |
| 2 | 225121 | franckuestein |
| 2 | 1580039 | asche |
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.)
