I just left a Star Trek RPG because the ship my character had been transferred to was the "Captain Carter Show" and we were all just his supporting cast. I wasn't allowed to explore my character's PTSD from the last mission of his old ship, and got told a couple times to edit my post whenever he deviated from "proper Starfleet officer behavior," meanwhile every other mission, the captain was getting stalked or kidnapped by terrorists, a cult, his own mirrorverse duplicate, and/or even a freaking Q.
Backing up a bit so the next part has some context, I played a Caitian character, which is a canon felinoid species. A couple years back, this other player--let's call her P--had her character come up to mine and, without any introduction or preamble, started publicly mocking him with cat jokes. Since he outranked her, he told her to shut up and wrote up a formal insubordination charge. All this was done in-character. My character remained understandably frosty towards hers, and even our captain at the time told her to leave him alone. Well she ignored the captain's orders and had a huge, raw fish delivered to my character, and he flew into a rage and wrote her up again. At this point, P went crying to the admins, claiming that I was harassing her OOC. Apparently she didn't think anything her character had said or done was wrong, and she refused to face consequences for her character's behavior. I was forced to drop this plot point and my character forgive hers.
Anyway, P had characters on every other ship except the one I was on, which was why I chose to leave the board instead of just asking to be transferred to a different crew.
A couple days after I left, one of the admins created a Japanese character and named them Hiro Shima. Which is a pretty big freaking Yikes, and several people complained about it. The admin apologized and said they would change the character's name, but P stepped in and not only insisted the character name was funny, but she wanted to see him eat "flied lice." Which all of a sudden puts her character's behavior towards mine in a whole new context. She's not just species-ist trash in-character, she's racist trash IRL. And when she was criticized for her comment, she just dug her heals in and claimed racist humor had been around for forever like it was some kind of proud legacy she was holding onto, or something. So many people left in protest that they had to shut down two of the ships and reshuffle the remaining characters. P's captain character was demoted, but she's still allowed to play on that site despite the fact that she's a liability that's costing them players. And a horrible RPer. And a horrible person.
I got out of there just in time.
