TSN fandom had such a bizarre reaction to whether or not it was RPF. No one knew how to tag anything at first and it was this big ordeal over whether movie fic should be tagged as RPF, but if that would confuse people who shipped RPF for the actors. And there were so many author's notes stressing that movie fic was based on the movie characters and not the real people because people were worried the real Mark Zuckerberg would find the fic through the power of the internet and sue them. What a wild ride that was. Good times.
