In the earliest days of my internet experience, I remember being able to do a web search for a phone number and sometimes actually find something useful. That said, this niche has long been dominated by some of the fakest, most scammy, bullshit sites on the web. From calling themselves “free” when they are not, to the fake “searching”, “sifting through results”, “correlating records” wait screens that are much like the deceptive, manipulative, and nontransparent airline industry, to the mentally manipulative exclamation point in the red warning triangle to tease you that there might be criminal records.
