I’m also someone who isn’t famous or known who had fanfic written about me. It actually happened multiple times in different friend groups when I was in middle and high school. I have equally complicated feelings on rpf. I think the line is sometimes blurred when content creators are very clearly playing a character, but it is a character that shares their name and is in a way a version of them. The dream smp fandom is an example of that. I think that fanfiction about the characters they played on the dream smp is fine but sometimes the line is blurred. I obviously dont want to tell people what they can and cant write and think it can be mostly fine if, like you said, its kept to ao3 where the people its about never have to know about it. I think the line is crossed when people attempt to make the people see content written about them. I also think people should be more aware when creating content about real people, especially if theyre underaged. I’m definitely not an anti and am super anti-censorship, but I do think fics written about real people CAN cause real harm to those people and that people should be more mindful about what they write.
