We don't know how Zillow is optimizing its search algorithm, nor would your proposed test eliminate all (or even sufficient) sources of coarse and fine tracking.
And the point, again, is not this is what Zillow/Redfin/etc. are doing. It's that the contention "online real estate listings eliminate the possibility of racial discrimination" is unsound because online real estate is also prone to racial bias. Facebook was just caught serving racially discriminating real estate ads last year.
If you want to claim that online real estate listings are bias-free, that's a claim requiring proof that the algorithms used do not have implicit or explicit racial bias. It does not have to be proven that such companies are racially discriminating to show that the opportunity for racial discrimination still exists online.
And given that this is a basic and tedious point to make twice, let alone half a dozen times, I will consider the point made unless it is actually addressed, rather than some adjacent claim that was not made.
