Makes sense, and a "this is why" on the flag would genuinely help.
Just to be clear on my side: the focus here is socializing — it's a community/chat hangout — and the mature flag gives the wrong impression about what the site is. I'm not trying to gut the site to chase the flag off; that would defeat the purpose. But I do think it's important to understand what triggers flags, because right now it's a black box.
Honestly, on the 29th I got hit with a privacy policy strike, and then out of nowhere it was removed again by the bot/person — and I hadn't changed anything. So I have no idea what I did wrong or right. That's the frustrating part: without knowing the trigger, I can't fix anything even if I wanted to.
