Oh, I'm kinda new :/

So, while flying around in noclip at the level woth paradox poster, i found that way back out of bounds there's this black box that when I went into I got tped to chapter 8, I think these boxes are in every level but I'm not sure, I'll provide proof later, if we are gonna allow this skip, can we call it ringportal? Edit: I think I saw a white wall box next to it, also can this be banned unless it's a separate category
