The Jenny mod still exist, its just under someone else right now, and i read that they soon ready for a new update for it.
(Mod now called Fapcraft, but its website for download has been flagged it as a virus, even though the mod was originally safe on that site) (Edit: the website for it is down because the new owner is keeping it down until they have a new update ready. Hopefully)
But yeah, its annoying when they take mods like those, because they think it damages the game, when in reality they just dont like the idea of people making lewd mods and not about protecting children and ect..
Cause lets face it, Minecraft is popular BECAUSE of the mods and games about it.
