Topic: Non-safe posts containing characters owned by underaged people.

Are NSFW posts that contain characters that are owned by someone who is underaged reportable?
If so, what is the process for doing so?

I think any post (NSFW or SFW) with a character owned by an underage person is reportable. If they could otherwise file a legitimate takedown, but can't because they're under 18 and can't come here to do so, that would be a reason to remove the post regardless of it's rating. As for how to, you can Report it and explain the character owner is underage (you'll likely need to provide proof).
