If companies could put ads inside our anuses do you think they would?

Companies would, and have, killed people just to make an extra cent. Of course they'd do this.

Depends of if the theoretical anus ad has a higher potential profit than expense. If the ad just mysteriously materializes there, and stays there where you'll never be able to see it outside of a colonoscopy, probably not. However. If it causes it to come out each time after you take a shit so you're face to face with a Tums advert when you go to flush, oh yeah absolutely.
- So what you're saying is they'd only advertise in high-traffic anuses...
- So an anus printer?

There is ads in public toilet, so sure, they'll put ads anywhere.

There is even toilet paper with ads on it. Does that count as "ads in our anuses"?
- Depends on how far you push it in.

The capitalism system is design to maximize and prioritize profit above everything else, and will do it if there's no resistance.

If put ads inside peoples' ass increases profits, companies would try for sure.

- I mean, branding is a thing too. You don't see J&J slapping their name on porn sites either, even though that's a cheap form of advertising with massive impression numbers.

"Your poo will be back, after this word from our sponsors"

When the benefits outweigh the costs they'll do.

I recently added some Taiwanese porn sites to my wank rotation. And while some of it is good, many studios have this annoying habit of putting temporary tattoos of adverts on the performers' bodies, usually on an asscheek and on the lower abdomen. I can't read the ads, but I'm pretty sure they are for gambling websites.

What the flying fuck?
- Yeah, it's really gross. Totally ruins the mood for me. Fortunately they're not hard to avoid

Probably not, but they'd definitely patent the method.

They would and it would be the first time you loved ads.

If you look at your poop in the toilet, then yes they will put ads in your anus. The ads would of course come out with your turds.

Embedded into cheap food that then becomes an ad in your toilet. But for a “pro” subscription you can shit without ads
Would they be like a sticker on the turd with the message, or more like a 3d printed brown thing?

You can bet your ass they would.

Heck, they would shove them in your dreams if they can (and they will, using neuralink lol); and then find crevices on the laws to navigate through, like crabs side-walking to move forward.

Bruce Bethke, the guy who actually invented cyberpunk and wrote the story Cyberpunk, wrote a book Head Crash. In which the VR hotsuit includes a "ProctoProd®" for bass. Bruce's predictions have turned out more accurate than anyone else's.

That would be shit!

no because you can't see up your ass

But other people can. It's all about the target audience. You would actually get paid, to show ads in your ass, when someone has a clear view into it. People with ads up their asses are just the medium to deliver the ads.
