Zillow has rental management services - i.e. there are people who pay their rent though zillow.com

because securing housing is a big part of residing somewhere?

I'm more so wondering what public data on these sites is really useful for finding/building deportation cases. It looks to me they are wrapping a bunch of scrapers into a product and selling it as "intelligence tools".

Many companies share non-public data with law enforcement if asked nicely.
