Would you be willing to confirm your phone number with Warpcast via SMS (wouldn't be publicly visible):

1. Gave you an algo boost
2. You could see other users verified by Warpcast

Working on Farcaster and Warpcast. Longer thoughts at https://dwr.email

This is moving too much towards web2.

I know phone numbers are meant to fight spam (even though unsuccessfully, as we see with Twitter). But in web3 we can do other things to fight spam, without involving phone numbers and similar stuff.

So I wouldn't confirm my phone number.
