Hello, I understand why this rule is being put in place but I want to clarify what exactly does qualify under ‘sexual act between a human and a lifelike “feral” animal’. For the purpose of it I will post few links from FurAffinity as examples, and if even linking some of them may cause problems feel free to edit them out of this post.
First of all, I believe any fantasy animal, be thier unicorn, a dragon, a gryphon or MLP pony or zebra or any other character from such aren’t restricted and can be freely be posted in artwork that depicts them engaging in sex with humanoids (also I assume the rule includes any near human humanoids like elves or orcs), even if they’re not talking to show their sapience or are shown in scenarios of dubious consent.
Also I believe pictures of real life “feral” animals that do not contain humanoids engaging in sexual acts with said animal are free to post, including pin ups showing their genitalia, the character masturbating or engaging in sexual act with some other animal character.
Now, the most easiest case for when an otherwise animal looking character may not fall under this rule - when they show clear intelligence by talking in the picture. Like this
https://www.furaffinity.net/view/31810357/ or this
https://www.furaffinity.net/view/28816738/ Both show that is pretty much a horse in some manner of sexual contact with a humanoid, but they, in addition to human like emoting, talk, either complete sentences or exclamations like “Yes!” or “Oh god!”.
Then there’s examples where animal character emotes but doesn’t talk, but they use non animal exclamations like “ah”, for example
https://www.furaffinity.net/view/28075587/
Also, just the pictures without verbal text at all, but with the characters showing human like emotions, eyes or blushing
https://www.furaffinity.net/view/36338319/ https://www.furaffinity.net/view/26810856/ And then there’s also images that have animal character “behaving in non animal way”, as was said in discord in reference to the animation of a (non feathered) raptor performing a blowjob, so perhaps the previous picture of a horse in reverse cowgirl on a bed or this picture of an animal character grinning and propping up humanoid character so he can engage in sexual activity with other animal character
https://www.furaffinity.net/view/37619736/
There’s also this image
https://www.furaffinity.net/view/36240098/ where the animal character is in non animal or realistic situation, but is not showing clear consent, so it only leaves such characteristics as human like eyes and emoting.
In the same vein there’s this picture with a character that passes a few of previous milestones and in general depicted as sapient but not talking, coming up to the human character and performing blowjob, which is not something animals regularly do, while looking up to PoV with human like eyes.
Also, what about sequences of images? For example here the previous character exclaiming and emoting in human like way
https://www.furaffinity.net/view/37928290/ and here’s the next image where we only see a close up of her genitalias and humanoid penis penetrating it. If, let’s say, individual pictures of former scenario were okay to post and the later wasn’t, would the fact that these pictures are in sequence matter, thus allowing the latter too? And it actually very important question, since a close up like that could be in a sequences of images that has animal “feral” character who talks and behaves in non animal like manner or even with a fantasy creature, for example a picture of a humanoid engaging in sex with a unicorn and the next picture that is close up of their genitalia touching, which can look like a picture of a regular horse, for example. This also may present a situation where a comic page as the whole may be okay to post, but a single cropped panel isn’t.
Sorry for slightly disjointed post, hope it will help to clear at least some vagueness.
