Not everyone is able to do 33 reports per day.
A lot of moderators have exams to study for at this moment in time too and they'd rather focus on exams instead of moderation duties.
Also, as well as reports, there are a lot of duties a moderator must do. Some prefer to focus on other areas of moderation instead of just reports.
May I mention, 33 reports can take up to one hour. Maybe even more. The quality of some videos are absolute trash in some reports and we need to ask for opinions if we're unsure about a report. That is time consuming.
I'm pretty sure most moderators will be less busy when exams are finished.
School > Cube
Let me add on,
Aside from looking at reports, mods still have to look at appeals which will take another chunk of time. Having duty/duties in-game etc. Sometimes they will need to set their priority and put their real life things ahead of cube craft. Like studies,exam because they can affect your future. Your report will get done, eventually. As I said, Waiting can be painful, but patience is key.
