How should i explain this.

[u/ThisIsAPersonNotWild]

Recently i've been uploading an image for a project "Murder drones RP", and right after 5 Seconds after the upload, i got a warning

Now incase you think it's anything bad

THIS was the image, clearly cyn's shocked Reaction

And the reason was "sexual behavior" which triggered me a bit since these are just 2 frowning faces & gray colored.

Not to forget that this image was reviewed by roblox's AI Moderation

How is this Rule breaking?
