Are you saying the golden showers story originated on *chan?
I remember when the dossier first came out, around January 2017, there was a story on Reddit or maybe it was pol, where there was a long post by someone saying “OMG, I can’t believe they took my fake post from July 2016 and ran with it.” He had links to some larp about Trump and the golden shower and claimed it all came from him. It was discussed for a couple days and then I didn’t see it after that.
Yes; was originally written about another candidate and then adopted for Trump ... Given to never Trumper who believed it and forwarded along. FusionGPS version near verbatim with some extra “details” added by Nellie ... Let me see if I can find. When Steele dossier was published the guy who first wrote it couldn’t believe what happened lol
