I used to justify it as collaborative writing, but I couldn't get past the fact that if you just glued together the replies in sequence you get this weird amalgamation that doesn't flow nicely due to writing style or perspective. So if it is original content and you want to publish it at some point, you need to rewrite at least half of it to match the other half. Or if you want to alternate perspectives, you need to fill in the gaps from the right character's perspective. I am not saying that isn't a great way of putting it, just expressing why I don't explain it that way anymore.However, I'd like to add, it depends on if you're just a casual dude or an aspiring writer. Society may not look at the basic stuff in a positive light, but some people write books worth of content here. Whole books! One day, some of us are gonna be millionaires off all that literature, just you wait and see.
So yeah, just say you're a budding novelist or some other such thing, and that you collaborate with others on books there. And if they ask where, they're getting a little too deep. Gotta keep your ideas to yourself and your associates if you wanna make that money.
