This is correct, however, the exchange of phone number has to be parsed through the text exchanges on the app (regex dashes and 10-11 digits....simple yet creepy), validated with an actual person (no fake numbers!), and Facebook needs permission from tinder to process such information.

As developers this isn't hard to implement, but it is a bit extreme.

There is also the question of business contacts, whom I have only had connection with via Voice Call and Text message (no external app and permissions given), showing up in my feed. Of course, this could be permission given on THEIR side that is reciprocating on my end, but again, this implementation is also extreme (ly possible).
