NGL I don't plan on letting my daughter onto AO3 or other fanfic sites until she's at least 16, unless someone creates some kind of effective (kids can always find a way around with enough commitment) parental filtering mechanism. I may download stuff for her to read offline on an e-reader, but on the site? Absolutely not.
There's stuff I saw in fanfic that has left scars- even stuff I saw as a young adult, but the world we live in means you better be ready for that by then, the way it's all so casually tossed out there. It isn't in the comments or whatever. It's the actual content. There be dragons, and that is a serious warning.
Frankly, while I find the people who operate AO3 to have a kind of libertarian integrity, I do not think they are interested whatsoever in preventing exposure of the underage to those sorts of things. Any parental filter will have to be third party mechanism. This house will have some kind of serious parental control on the internet, which if it is useful at all will probably block AO3. Sorry. You know what's on that site.
I can't be the only millennial parent in fandom thinking of this. I'm sorry but kids need maturity and emotional control before they're even accidentally exposed to some of the stuff I've seen. Filters work great if you already have that, but you need to have it in the first place. I've seen a lot of great art in fanfic, beautiful things that touched my soul and/or gave me real time with characters I loved. In a lot of ways fanfic is a natural and ancient artform, people riffing off of others' stories since stories have been told. I don't want to deny that to my daughter, but the scars I have are spiritual stumbling blocks that would have destroyed me if I didn't have a real foundation as a person first.
I worry about so many things these days.
