Practically, and literally impossible. There's CP and other illegal material being posted in these subs every second. Without API access, you have to have dozens of moderators at all times checking every single incoming post.
It's like these people are coming in driving cars and Reddit management is offering a sturdy pair of walking shoes to try to keep up with them.
C-level management seems to be an insular royal court far removed from the actual mechanics of what makes their company run and not familiar with where the hard work is done and what's the value lost in getting rid of it. It's destructively hierarchical and makes things undirected, disjointed and clashing.
Incoherent executions and incredulous decisions abound. The current practices are clearly idiotic.
Oh well? That is a job for the police to deal with, not an unpaid moderator with a hobby. If you want to help out in your free time, cool, but beyond that, who cares?
