True, requiring phone number are to prevent sybil attacks and are for accountability.
- Nextgrid 8y agoPhone numbers are extremely easy to obtain. This won't achieve anything in the long run.
- etaioinshrdlu 8y agoCan I have 100 phone numbers for free? I don't believe it is so easy.
- Nextgrid 8y agoThe same way we have the robocall situation (thanks to shady telcos that turn a blind eye), the same way this system will be bypassed with similar telcos offering massive blocks of numbers at very cheap prices per unit (Twilio numbers seem expensive at small scale, but I guarantee you will get those prices down if you commit to getting like a thousand of those or so at once).
- dymk 8y agoWhat you're saying is, this has increased the cost of creating a Twitter spam account from practically zero cents to... what, 50 cents an number? A few dollars per number? That's a huge leap, and it sounds like requiring a phone number is a great way to increase the cost of spamming.
- etaioinshrdlu 8y agoEspecially considering your average user already has a phone number and its basically free to verify. It only has a cost for spammers.
- Nextgrid 8y agoIt has a non-negligible privacy cost.
