@Primethion2021My understanding from a news video on YouTube is that the Sims team has already addressed this mod in a tweet, saying that anyone using it would be banned. I'm not allowed to link to information about the mod in question, but if you google "sims team addresses disturbing mod" you'll find the YouTube video and some news articles about it.
I won't link to the official Sims team tweet (that feels weird, but if you scroll up they discuss the mod) but they said on February 22, 2021:
"These types of mods have deeply disturbing content, are not authorized by EA, and their use violates our User Agreement. If we detect players using this kind of mod content, they will no longer be able to play the game and will face permanent EA account bans."
[Edit: and if I'd looked at the image I would have seen that @Idiosyncratic53 already screenshotted it for you.]
I hope that helps! and I agree that those kinds of mods are disgusting and shouldn't be tolerated.
P.S. I don't work for EA and support your attempts to report it! they do know but they have to go to all the different sites that might host it and have it removed that way.
