At least in canada with the national do not call list, I’ve found I receive very few robo calls. For those I do if I wait to talk to a real person and then press as too who is calling me so I can file a report they hang up quick and I don’t hear back.

> Doesn't Google Voice solve this problem? Or perhaps there are restrictions I don't know about.

Only sort of. I wouldn't be surprised if Facebook rejects Google Voices numbers and will only accept a real-live carrier numbers. It seems pretty easy to do, given how often my GV is rejected by sleezy services I'd like to give a throwaway (e.g. peoplesearch opt-outs).

However, I'm not going to personally test this theory by attempting to give a panopticon like Facebook even my semi-throwaway GV number.

Let me surprise you then so you can stop making false speculations - you can use a GV number for Facebook 2FA.

Even if FB was not allowing Google Voice, you could give FB the real number and give throwaway GB numbers to recruiters.

That would solve the issue voiced by OP

I imagine most people would have no idea their profiles could be searched via phone number. I didn't know until today.

If it never occurred to you that this could happen, you would not take steps to prevent it.

We don't have Google Voice in Australia.

Only for US and Canada.

Only US actually.

Because of all the issues with (1) terrorists, (2) foreign state influencers, (3) spammers, Facebook tries to block Google Voice as much as possible
