Look at the below example. James Gunn was fired from "Guardians of the Galaxy 3" by Disney after his offensive tweets resurface. He was fired in 2018, for tweets that were written between 2008 and 2011.
Look at James comment. He mentioned that he has changed himself and like his new avatar.
“I used to make a lot of offensive jokes,” Gunn wrote. “I don’t anymore. I don’t blame my past self for this, but I like myself more and feel like a more full human being and creator today. Love you to you all.”
So, the question is that should a person's content be hanging around forever by some LLM?
There is option in facebook to delete your content. What if LLM learns it and keep on using it even though it doesn't exist at source?
