There's nothing to see here, it's just that the amount of monthly reports coming in is much more than what the active mods can handle because most of the cases are handled manually, they're not bots I never expected them to handle all monthly reported cases, most of my last month reports were left unhandled I guess mod didn't pick it up
This is hardly the true reason for so many unhandled. In February, I sent almost the same amount to moderators as this month and about 10 of all almost 30,000 reports were unhandled. At the heart of this large number were single posts, such as old bumps or posts that no one answered. I myself have repeatedly encountered the fact that I asked the moderators a question regarding why the post was not deleted, and the answer was just similar to what I wrote above. This is especially true of old discussions, in the year 2017-2018.
I think moderators are free to process 100,000 reports per month. It is unlikely that there is a correlation between the number of unhundled reports and the large number of reports sent.
