probably there is a disclaimer of some sort, and people think they can handle it. but also, even people who worry they can't may be desperate for a job.

i work with people who have experienced terrible things, but it's a little easier to manage because i am hearing about it (only to the extent that people want to talk) and not seeing it, so i get a little psychological distance. my environment is very supportive and i'm hearing things sometimes, not watching it hundreds of times in a day. even then, people in my role are at decent risk of burnout.

like, you never know when you're going to hear a thing that just gets to you.

doing what these mods do for hours and hours a week without support seems like a recipe for secondary trauma and burnout. edit - and yes, i'm pretty sure their environment amounts to "suck it up and keep going."
