Requiring a phone number simple way to mediate and bottleneck people trying to create bot accounts or abuse the service and also create a positive user onboarding experience to actually use the app. I disagree with the need for a phone number, but it makes the act of "registering" much easier. There's a reason Gmail and other similar "huge" services also require phone numbers for registration.
