Even with such methodology and you use
exactly 4 seconds to report each post, you still spend lots of your time.
24190 reports * 4 seconds = 96760 s
96760 s / 3600 s = 26.87h
Anyway, i wonder how would result of next "Top reporters" (which shared by theymos) looks like.
In February, it took an average of 2,5-3 hours. There was a lot of free time, winter period. I decided to take a break from the markets, investing, charts and other things. Now, with the onset of spring and a more active schedule, I will no longer be able to send such a volume. But I think I can sent 10 000 reports a month.
