Several years ago I tried to make a Twitter account. It got banned before I posted anything. I hadn't even subscribed to any users. I was going through the settings, and then \bam\, banned for being a bot, or some such nonsense. Nothing of value was lost.
Yeah, I had to get a separate number just to please twitter's automation.
Their approach is somewhat understandable - stopping bots is a hard problem, phone number in theory represents a material cost and a hurdle to someone who wants to rapidly register thousands of new accounts.
This is brought up every time this subject is discussed. Is a burner phone a normal thing that regular people have?
But no, I don't have a burner phone. I'm not going to buy a phone and a SIM just as some kind of non-solution to tech companies having a hard-on for invading peoples privacy.
