Believe me, I'd love to see nudes of her, too, but these are fake.
There's nothing that would imply that Keeki herself made these photos for public consumption. There are the moles, but you can easily see that the skin tone around them differs from the rest of the image, which suggests a doctored image. There's also the fact that the images have a ton of beautifying effects on them which would erase said moles, too, yet they are still there. On the other hand, a rather well known birthmark on her right breast is missing from both pictures.
You know it's fake when even the smaller chans don't recognize them as even plausible ones and Keeki has amassed a lot of haters during her activities, this would be the ripe time to exact some revenge on her by besullying her image, photos fake or not. Yet that doesn't happen, which only suggest that these photos are so fake that not even her detractors would risk getting laughed at for trying to pull it out. Said haters have also never found any link to websites that would suggest that Keeki once had a subscription-based private mailing service.
If it were revenge porn, it wouldn't be censored, or dripped out on the internet one by one. We'd also have further proof that someone received these images with additional texts and the like. It also wouldn't look like something from an OnlyFans/Fansly photoset, taking quick pictures of herself and uploading them in an album, something that's very common in the scene. Just take a look at the thousands of other leaks on this website.
Speaking of, I actually tried to look into the origins of the photos and while I didn't find them yet, I've found at least 3 or 4 candidates that could have been used for faking purposes easily. They didn't have to be these exact photos, a bit of Photoshop could have achieved the same results on other images as well, which just futher confirms that all of this is the work of a single person who found a set of nudes from a similar looking girl and is trying to mess with the internet whenever he's bored.
