Within the recordings themselves, users willingly surrender personal information—information that is especially valuable in these review processes because they are so specific. Uncommon names, difficult-to-pronounce cities and towns, hyperlocal oddities.… I heard people share their full names to initiate a call or offer up location-sensitive information while scheduling a doctor’s appointment… the recordings capture people saying things they’d never want heard, regardless of anonymity.… There isn’t much to keep people who are listening to these recordings from sharing them.
