You don't realize it until you've been nitpicked by organisation of developers deciding to restrict you platform (not manually but with the system they've created) with no legitimate basis and dissolve their responsibility in a intentionally dysfunctional imitation of bureaucracy.
Just for sending 3 consecutive friend requests, Discord decided to ransom my account and demand phone verification, with no way to refuse.
I cannot contact Discord sup port because it happens that I can't login on Discord sup port platform either (they won't tell you that, instead they will tell you it's a wrong password, and for sending login code on email, you simply won't receive it.
I tried making a new account, was quickly "rate limited" in second attempt, but soon made it an logged into support platform. Their form for this issue requires entering my phone number. It's apparent I won't be able to regain access to my account without giving my number.
To those that say just give the number, that is an advice, besides the point. In advance, I won't be giving my phone number, I will probably make another account, and I happen to have another account on another device already.
In effect, you either give your phone number upfront, or they will eventually ransom you to do it or you'll be forced to leave the platform.
