Just bid low. X ads work by bids on an audience. Audiences with low bids are extremely cheap. E.g. reasonably targeted US audiences used to cost $1.50 or more per follow (I don't remember click rates), while random bottom of the barrel follows could be obtained for <4c (you'd end up with non-English speakers in third world countries with little on their profile) That said, even "quality" audiences on Twitter are really and miss depending on what you try to achieve.
