Here I copy the &quot;dead&quot; message from &quot;uola&quot;:<p>&quot;Yes, phone numbers are public enough that they are shared everywhere, but unique enough to lead to a single person not to speak of that persons movements. And &quot;just use twilio&quot; isn&#x27;t a motivation for using phone numbers in the first place.<p>If he had said &quot;the benefits of finding friends are greater than the privacy implications&quot; or something like that there would at least been a case for a discussion, but now he&#x27;s seemingly saying &quot;oh, if you really care about privacy you could&#x2F;should use a fake phone number&quot;.&quot;<p>---<p>Personally, I don&#x27;t know how &quot;a fake phone number&quot; setup can be implemented, especially in the countries where each phone number is assigned to one ID at the time of purchase, so to me &quot;use a fake phone number&quot; sounds like &quot;let them eat cake.&quot;
