Anyone else ever notice that the majority of posts on this sub are obviously posts made by 4chan users instead of redditors?

Like, look around at some of the most popular threads here. They're all genuine 4chan posts, including the n word on blast. What the hell? How is this sub so heavily moderated by 4chan when it's literally supposed to be a sub for, quote, "documenting the existence of the subversive and insidious growing minority of self-identified 'feels', or 'emotionally charged autists' on 4chan."?
