Twitter used 2fa info for advertising
 

So, as many suspected Twitter was using your phone number and email address collected for 2FA security purposes to spam you with advertising.

Twitter's handling of users' email addresses (perhaps alos phone numbers?) is the exact opposite of "securing their accounts":

Twitter allows a user to enter an email address and set it up to receive notifications without verifying the address. Then that address can be used to reset the account's password. If the address belongs to someone else (such as if it was misspelled, if the email account was closed and the address given to someone else, or if the user specified an arbitrary address so as not to be bothered my email from Twitter and its "partners") then that someone else would receive Twitter's notifications and would be able to reset the password.

I never signed up for a Twitter account, but I twice had to reset some user's password to stop the flow of someone else's Twitter notifications to some of my addresses because Twitter does not provide any other way to tell "do not send to this address", and doesn't bother to verify the address in the first place.

I have multiple Twitter accounts (personal/hobby/EMD) and have dedicated e-mail addresses on an own domain for each account - if I had received any spam e-mails to those dedicated addresses I would know - but I haven't.

Phone number? I tend not to answer any calls from numbers I don't recognize, but it is possible I suppose.
