Summary
It’s a more restricted way than allowing users to search for user profiles using a person’s phone number, which Facebook restricted last year after admitting “most” users had their information scraped.Facebook gives users the option of allowing users to “look up” their profile using their phone number to “everyone” by default, or to “friends of friends” or just the user’s “friends.”But there’s no way to hide it completely.Security expert and academic Zeynep Tufekci said in a tweet: “Using security to further weaken privacy is a lousy move — especially since phone numbers can be hijacked to weaken security,” referring to SIM swapping, where scammers impersonate cell customers to steal phone numbers and break into other accounts.See thread!
