As @mikewarot said, too, look for reviews of the given service elsewhere (and then determine how reliable (another thing I wrote a while ago: https://antipaucity.com/2006/10/23/authority-issues-online/#...) that site is)
Businesses can afford lawyers, which civilians can't afford to risk the encounters with, so any wide-scale review sites that told the truth would rapidly get shut down, or bought off, a sad reality these days.
