Most notably in Part 3. The Tower of Grey stand resembles a Stag Beetle, the crusaders find DIO’s location using a photograph of a fly, and a character is seen eating live beetles.
in part 3 several adult women are attracted to a 17 year old character. there is also a pedophile orangutan, which sounds absurd. in part 5 an 18 year old makes inappropriate comments about a 15 year old.
Rape as a word is never outright said, but it is mentioned and implied in Part 3 (as part of a character's backstory), Part 4 (as something a villain has done; the villain is quickly defeated and practically killed) and Part 5 (as part of a character's backstory and as part of a villain's powerset, unfortunately)
In part 5, a man is tied up, gagged, and forced to watch his partner get hacked into pieces. He later kills himself by swallowing the cloth he was gagged with

It’s par for the course in Jojo. Specifically, in part 3 the character Mariah has every bone in her body broken after she is crushed between two cars. She lives, however.
The character Cioccolata has a reputation for torturing his victims, along with his partner Secco who records videos of the victims’ faces. The two are vaguely shown brutally torturing a gay couple early in part 5, and other grotesque examples of what Cioccolata does are listed. Also in part 5 is “the torture dance”, wherein main characters dance while another character’s retina is burned as his disembodied head is dangling from a fishing line by the eyelid. Despite how gross that sounds, it’s mainly played for comedy.
In the first couple of episodes of Part 3, the protagonist falls down the stairs after being attacked by an enemy. The protagonist uses his power to survive.
In part 3, a character’s eyes are scratched and he is temporarily blinded (not graphic). In part 5, a character’s head is dangled with a fishing line by the eyelid.

He “adopts” the baby but theres no mention of legal adoption processes. Also in part 4, Yukako kidnaps Koichi (they are both teenagers of roughly the same age.)
Characters get poisoned in Part 1, and there is some implied substance abuse in Part 5 (particularly by teenagers in the background of the story). Nobody ever overdoses on screen, however.
many backstories of main characters involve the death of family members. because the story revolves around one bloodline, many members of it do pass away.
In part 1, the main character’s father is killed. In part 4, a woman’s father (the main character’s grandfather) is killed. In part 5, multiple characters have backstories involving dead parents.
in part 3 there is an episode called “Justice Part 1” where a character named hol horse is forced to shove his hand into his own mouth and then he vomits. I had my friend skip over the scene for me but I know that there’s audio and possibly visuals.
In part 3 episode 19, there's an antagonist baby (with the intelligence of an adult) who soils himself and then another character mixes it into his food and has him eat it to punish him
there’s multiple instances of on screen poop. in part 3 there’s poop on screen during the death 13 arc and polnareff shits himself in a bathtub to escape someone (that sounds insane lmao) during that weird part where he’s a kid, a few times dog poop is shown, turtle poop is shown, and alligator poop is shown.
In Part 2, the New York city police are corrupt and racist. A character's grandfather in Part 4 is a cop, but is only part of the story for a very short time. One of the characters in Part 5 is an ex-cop; the police themselves are repeatedly portrayed as openly corrupt.
There is a character who is known by a different name than he had a t birth, but other than the name being mentioned when he was introduced everyone calls him by his chosen name.
implied drug use via needles happens in pt5; it isn’t actually shown, but it’s heavily implied. Also in pt 5, a character gets needles spawned in his mouth
Yeah, in part 5, a character's backstory is meant to put a truly evil light on them, as they were a doctor that did things like put light doses of gas on people so they wake up during surgery, but it's censored.
Most of the time.
in part 8 an antagonist has the power to give cancer to people that touch an specific something, it's explicitely mentioned as cancer and it's fast and a bit gorey
In the Death 13 episodes Part 1 and 2 Noriaki Kakyoin and seen in a dream taking out a pocket knife. He is seen on screen cutting into his arm and the scars can be seen multiple times. Towards the end of Death 13 part 2 it disappears.
Ep 6 of Part 6 has a suicidal character whose ability is that the injuries from his suicide attempts are reflected on to someone else. The main villain of Part 5 has "split personality disorder" and both personalities are sadistic murderers.
in pt 6 there’s a minor character who tries to kill himself several times. there is also another pt 6 character who tries to shoot himself but there are no bullets in the gun.
there is an incredibly large amount of curse words/obscene insults throughout the show. there are also several gestures, most notably in part 6 when a character lists different variations of the middle finger.
An orangutan watching a girl in the shower, Joseph spying on Lisa Lisa while she's taking a bath, Hayato spying on Kira and even taking pictures, the list goes on.
Although there is no explicit antisemitism, the nazis in Part 2 are handled very poorly which viewers should be aware of. The anime adaptation doesn't include swastikas/iron crosses and refers to them as "German Soldiers", however the character Stroheim still regularly throws up the nazi salute. He also receives a touching sendoff, gets more screentime and fight scenes than some main characters do, and is well loved by the fanbase. The villains regularly murder nazis which is very sexy of them though.
In part 5, the main character remarks on a prisoners abnornally tall and large, fat body wondering how he even got into the prison cell in the first place.
At the end of part 2 and in certain parts of 3, Joseph is shown being racist towards Japanese people. In part 6, there are scenes involving the KKK wherein they beat and hang a man of mixed race. He survives, however.

A character in Stone Ocean is a priest and he is shown discussing Heaven and how to get there with another character. The idea of learning how to go to Heaven is his main motivation.

Part 3 shows the penises of two babies, the cleavage of a woman, and the butt of a young girl (briefly). In the comic of part 5, a teenage girl’s areola is shown in one panel, but not in the anime. In part 6 there is a naked man’s butt shown as he showers, and the main character strips to be searched before going into prison (though only the top of her breasts and part of her butt are shown). Many characters dress somewhat immodestly but its not too bad.
in the animated parts, there are no real sex scenes. in the not yet animated ones (7 and 8) there are a couple implied sex scenes but no one explicitly loses their v-card.
an old character in part 4 is referred to as senile several times, as he has trouble hearing and sometimes gets confused/misinterprets instructions. however, it is minor and he does not have a diagnosis.
Ep 11 of Vento Aureo shows Narancia's backstory which involves him becoming homeless after his mother's death, there are some shots of him sleeping in alleyways and eating food from bins
