I’ve never actually heard or seen someone honor such a request online or IRL, and it would sound ridiculously stilted if they did. Where is Rumpelstiltskin’s coat? Rumpelstiltskin must have left it at the bar. Will someone please text Rumpelstiltskin and let Rumpelstiltskin know?
the only recurring reason to use a pronoun for someone on a place like this is usually to talk about the original poster, who is already lovingly abbreviated “OP”, shorter than most pronouns
