Unfortunately, reports have died down in recent months so I imagine this effect is more noticeable. Again, it's not a problem in my opinion, but probably more noticeable. I miss the days when I woke up to hundreds of reports, it's somewhat therapeutic to deal with.
It is easy to determine whether it is due to an active member or due to a decrease in the spam rate in the forum.
I remember there was a user who used an AI bot or something similar to identify plagiarism and because of him hundreds of accounts were banned.
So by reading the reporter username, you can get a general statistic.
I don't have many reports per month and the french section is not the most active, so most of my mod actions are done without a report.
How is the payment then? In other words, I can create many accounts, spam with them, delete topics and reap profits or I can tighten the deletion criteria to get more payments.
