i'm a person who plays several characters played by the same actor. in my case i have 3 that i've played regularly, i have a certain type of character that i like to play and this actor just happens to play those roles often

i believe i'm in the "really like the actor and it's harmless" group, and i've met others who do this and they're not creepy obsessed, we just like what we like

that said, i see why it looks odd and i don't doubt some people who do this are weirdos. i think rpf is extremely strange. a lot of the behavior mentioned by others in this thread would be a red flag to me too. just saying some of us are harmless i promise lol
