I big reason that housing groups are filled with people posting looking for a room, rather than vice verse, is because Facebook offers a terrible search UI for actually finding suitable houses. I can't filter by location, rent, rooms, etc. etc. I have to instead scroll through dozens of irrelevant posts, then send a message to relevant ones and hope that I'm a suitable housemate and they reply back. Meanwhile, on websites specifically designed for finding roommates, I can usually search by location, price, rooms, gender requirement (if any), building type (e.g. apartment, house), etc. etc.
