You used the word ”anymore”.
Obviously, you are implying that Twitter required a phone number in the past, but because you did not specify the time of the change, we must assume. It could be that phone numbers are not required since an hour ago or a year ago.
Regardless, if it was a requirement, chances are high that a good portion of the 400+M users in this (supposed) data breach were encouraged to share their phone number with Twitter.
Not to dismiss your contribution but if you have to write ”anymore” I don’t see the point of your comment.
I suspect twitter did this to pretty much everyone.
This isn't what we are talking about. We are talking about requiring users to "prove they are human" by giving Twitter a phone number and then entering an authentication code that they text to that number.
It doesn't accomplish anything because I can get a new SIM card and a month of "unlimited" talk and text prepaid service for about USD 20(?). I didn't think of it much but looking back it is clearly a data grab.
This happened to me.
I made an account, not using a phone number.
I then did not use it, for something like a month.
I posted - and the account was suspended, I was emailed, "you have violated our T&C, please provide your phone number to validate your account".
I may be wrong, but to my eye, they were attempting by deception to trick and force users into handing over their phone numbers.
I explained I had no phone number, and I had not posted at all, so it was hard to see how I had violated the T&C, and the account was unfrozen, and has been fine since then.
