Where are you getting the "blog post about selling a house" from? The examples given are "Bajillion Dollar Properties S01E07" (which is titled "Happy Ending" and involves real estate brokers getting massages: https://en.wikipedia.org/wiki/Bajillion_Dollar_Propertie%24#... ) and "First Time Home Buyer Anal Fantasy" which I assume is actual porn. That seems much more like a human expanding their porn collection at work (and perhaps being disappointed that the first one they downloaded is just a comedy) than an algorithmic crawler.
