Look… this is going to sound exceedingly stupid… but shouldn’t they find a way to use convicted sex offenders to filter out CSAM? They are not going to be traumatised by it and it saves some other poor soul from taking the brunt. How do you motivate them to actually do it? Well first one has to flag, and a second one earns a bonus every time the first one flags wrong. Motivation aligned!

There’s actually a lot of logic to the general idea of hiring specific population groups that don’t get traumatised by the content they’re checking. Problem is FB (and other companies in the same vein) can’t be bothered to do anything except hire the lowest bidder.
