Referral based hiring means you don't get paid if the person doesn't get hired. So there is already an incentive to not waste one's time referring somebody that is unlikely to get hired.

Either way, this company doesn't appear to provide any solution, it's just inserting itself into the process as a middleman.

Well, the disincentive of wasting one's time (in practice that means generating an application link, or filling out a short form online) is much, much smaller than the potential reward.
