The R34 originally started from a 4Chan board and took off from there.

Rule 34. The fabled 34th Rule of the internet. The Rule is simple: if it exists, then there is porn of it. The Rule is always true. You cannot break it. No one can. However, what about the reverse of this Rule? If there is no porn of it, it does not exist. This is the unspoken dark side of The Rule. I quickly asked myself "is there porn of me?". I nervously typed in my name on some popular porn sites. I didn't find anything. As I went from one porn site to the next, dread slowly filled me. Pornhub. The Rule remains true. Xvideos. The Rule remains true. Youporn. The Rule remains true. I got desperate, so I went to more obscure and niche websites. Hentai Haven. The Rule Remains true. Nhentai. The Rule Remains true. Hanime. The Rule remains true. I even visited the dark web looking for anything. Even a crayon drawing would do. But as I clicked on the last porn website and typed in my name, I realized that I was slowly fading out of existence. Quickly I opened Adobe Photoshop and started drawing porn of myself. It was the only way. Head, body, arms. I was 25% gone. Legs, feet, knees. I was 50% gone. Now all I needed was the dick. This was the challenging part. I drew and I drew. I was 75% gone. My dick took up most of the canvas. I was 90% gone. I was almost done. I just needed the tip. I was 99% Gone. When I finished I was relieved. Somehow I had broken the rule. And when I noticed, reality began to collapse. Everyone should make porn of themselves to be safe. So yeah, that's why you should send me nudes.
