If anyone wants to do this, you probably want to use a private chat channel and vet the people granted access. I suggest a matrix instance. You don't want outsiders to be able to see what you're doing, and you want to the boosting to happen quickly, so you don't want to make the posts to bubble up through two algorithms. It seems like a fairly easy thing to do, and either we influence reddit or we force reddit to crack down on this behavior which seems like a win/win to me.
