Agreed but, in what jurisdiction does Twitter require phone numbers?

Cleaning house before due diligence.

Yeah, it's shocking they would say this when they do require phone numbers in many instances.

Many unexplained instances. (Twitter will claim a prior but unspecified TOS violation but thats a dodge, rather than a justification)

No mention of that fact that 'use another phone number' is quite an expensive thing to do in countries where a phone number has an annual fee of hundreds of dollars. Suddenly 'use twitter securely' has gone from 'free' to 'hundreds of dollars a year'. Perhaps they should announce this as a price change instead?

>countries where a phone number has an annual fee of hundreds of dollars. Is this a thing? I've never heard of it. Where?

You need a plan to have a number because it's difficult/impossible to get a number allocated to you as an individual. If we assume "hundreds" means >=$200/year, then the maximum monthly payment we can have for that not to be true is $16/mo. The absolute cheapest phone plans I could find in the US that weren't for alarm systems were $15/mo on mvnos like mint. In practice, I suspect few people are paying less than $25-$30 a month, or "hundreds" a year for their numbers.

Remember that phone numbers are only 10 digits long, so brute forcing all phone numbers is totally doable. Considering that, if you implement any flow that involves checking if a phone number is already in use, then you are effectively leaking to an attacker a list of every phone number that uses your product.

In the USA.

They range from 4 (St. Helena) to 13 (Austria), I believe.

It's true in the USA if you stick to the big providers... Ring up t-mobile and say 'I'd like a line with 0 minutes and 0 GB of data, just to receive verification texts for Twitter' and they'll probably quote you $200 a year or so...

$120 before tax for T-mobile for 1000 minutes, 1 GB/mo.

It might have some PR speak sprinkled, but it’s genuinely good advice, put more bluntly: “We can screw up, if it’s important enough for you to stay anonymous you should get a separate phone number and email” That is a good tip with every company. If you want better security, have less trust in the services you’re using. This goes to what victim blaming is. Yes. It would be great if the victim lived in a better world.…

In Germany and other countries you have to show government ID to get a GSM number. Phone numbers are like bank accounts: strongly linked to official name and identity. This advice is bullshit.

But you can abandon a number after you registered on Twitter. Doesn't help against agencies but against scrappers
