Did you use a voip number (e.g., Google Voice/Twilio/etc.) instead? Or somehow no number at all? Or a secondary (real) phone number, and Twitter somehow determined it wasn't your primary personal phone number?
Not pushing back against what you said, just trying to understand what factually happened.

But I didn't try to create an account recently, maybe they went back to requiring phone numbers.
Walmart recently deleted my phone number from my account for vague reasons but most likely because another account had the same number. That other account is my wife and the number is our VoIP line. I have no desire to interact with walmart through my cell phone so I didn't give it to them. So I used a google voice number, which is not my number, to get back in. Then they just bought my actual cell number from my credit card company and autopopulated the field. Jokes on me!
Ironically AI could fix this when trivial spam detection inference becomes cheap enough to throw away on every upload.
Holy moly, don't you have any law at all to protect people's privacy ?
I think Bluesky didn't require a phone number to sign up, just an email. Maybe I'm misremembering though and it forced a phone number so I had to provide a fake one or a voip one.
