In Birth by Sleep, Phil agrees to train Aqua without question. When Hercules asks why, Phil's reply is "Sh, pipe down kid! You and she ain't got the same attributes, if you know what I mean." Yes, he invokes the trope word for word. And then Hades meets her and gives her a once-over with a very creepy grin. It doesn't take tricky camera manipulation to see Tinker Bell's panties - they're rather obvious in some scenes, particularly when Ven first visits Neverland and the world logo appears.
In Kingdom Hearts: Chain of Memories, Larxene practically molests Axel on-screen, stroking his face, pressing her whole body up against him, and generally ignoring his personal space. It mostly passes for shipperbait in fandom, but Axel's expression is distinctly uncomfortable and distant, and Larxene's suggests that she really doesn't care whether he likes it or not.
Birth by Sleep has Master Xehanort, about whom some very nasty things are implied. He carries an eleven-year-old, unconscious Ven to Destiny Islands wearing a white shroud with no shirt underneath. That's odd enough on its own... but Ven was fully clothed before going unconscious, which suggests that Xehanort took it off afterwards. He also gets rather... excited◊ when Terra can no longer resist the darkness. When the one doing all that is an old man who says things like "at last, our moment is here" while executing a Grand Theft Me,it's no wonder he's seen as a Memetic Molester.
Even the manga likes to do this. One noticeable moment is when Sora goes through Ariel's belongings in hopes on finding something interesting for their quest ( it turns out Ariel has one of Ansem's Reports). An even dirtier moment happens in Kingdom Hearts II, with Sora accidently getting a glimpse of a naked Mulan. He did not take the sight well.
Instead of the random Red Shirt like in the original game, Sora talks to a woman before she's killed by the Heartless and it's implied she's a prostitute trying to proposition him.
All things about "Namine is being hold as hostage" in Chain of Memories suggested that Organization XIII, more specifically Marluxia and Larxene, is a child kidnapper and molester. Namine also always wears a dress with short skirt which exposing her legs, as if it was the Organization who made her dressed that way.
Don't forget the (as expected of Square Enix) all the Foe Yay and Ho Yay.
In Chain of Memories, the way Larxene harassed Riku Replica before she forced Namine to rewrite his memory, suggested that as if she's going to rape him. Not to mention that Larxene is a well-built adult woman while Riku Replica is barely an adult.
