I do wonder how far it is to the bottom (6) of the rabbit (6) hole.
the codes are everywhere. Every major youtuber with any kind of follower count is one of them - cause the cult controls the algorithm so while they will give anon's fake subscriber bots to make them think they are talking to real people - only word of mouth passes your video to anyone.
anyway, the point being shows of any shape or size of any place in media or internet - will have cult codes embedded into their thumbnails, titles, timecodes and so on.
