Does phone-walled mean you have to verify with a phone number? Are you unable to do it because it doesn’t work, or because you don’t want to give it your phone number?
Since you need to provide a phone number to sign up for Discord is the reason I never will.
There should be no reason for a phone number and nor do I want to waste my time trying to buy pass it with internet provided single use numbers.
Unless it is a service I must use, then I will provide a phone number. If it is a service I get to choose to use then I will never provide a number.
Yes to all 3.
Even times when I've given up and put in a real phone number that has never been used with Discord, it still just bans me immediately after verifying, so they basically just stole the number.
Most likely they don't want to. It's ridiculous that you would need to give your phone number for some chat program.
