I don't know why Twitter adds that authentication at Sign Up. I tried to create a business account but the Twitter sign-up process is $#*!ty hard. Why do I need to authenticate 10 times just to sign up for my business profile? What the hell robots will do on Twitter so that you are afraid of them? Make another identification part tight instead of $#*!ty sign-up puzzles. You wasted my 30 minutes on that.
