I haven't seen too bad stuff. There was one person who would use filters to make themselves look like a kid. I had arguments with the admins that they were a kid. It was a whole thing. They're still posting, too.
One time, I had someone that looked like a kid. The moderation process is pretty simple. It's just like normal Reddit, but you can see reports, and you can remove other people's posts and comments.
How much time does moderating cost (if the answer is "it depends", can you specify what it depends on and give a range)? Does having to moderate ever get in the way of life?
Life always comes before moderating, it's very much a hobby. At most, moderation takes an hour a day. Sometimes, it'll take 2 hours if I have nothing better to do.
I’m actually surprised it’s not that bad. Though I suppose people understand Reddit was moderated before last month so they wouldn’t post illegal content and such there
