I read about this prior to the election. It was being passed around. I'm not sure if there is some real merit to it or not. Reddit says it's manufactured from 4chan and was passed around and kicked up to news outlets. At this point i don't know what is real or not. This election has challenged any sense of reason.
/pol/ is giddy right now not knowing they've been deeply counter-trolled. While I'm still skeptical about this report being 100% factual, there is zero evidence that 4chan had anything to do with this. All they have is that a supposed-insider claimed in Nov 1st to have fed Rick Wilson (Buzzfeed guy) info about a sexual Trump scandal, and claimed that Rick Wilson totally bought it. Nothing specific about golden showers, getting back at Obama, prostitutes, or anything, extremely vague. Not to mention that people have been suspecting Trump of hiring Russian prostitutes for much longer than Nov 1st, in addition to this report having floated around months prior to then.
It's hilarious because right now people on /pol/ are posting screencaps of the reporting alleging Trump engaging in hentai roleplay while wearing children's pajamas, the silly people there thinking it's actually contained in the 35 page report. Trolls trolling trolls, so much disinfo everywhere, it's beautiful.
