Not mine and it sucks that this means I'm not welcome as FireFox contributor anymore unless I move countries just to register a monthly contract for a dedicated GitHub-accepted SIM card.
Once you trigger phone-number verification requirement your account is globally shadowbanned and support blocked pending SMS code verification. Aside from the privacy issue it's completely blocking people in the several countries (beyond the ones offially totally banned due to sanctions) to which GitHub won't even try to SMS/call.
Remember that registering a second account would be violating GitHub ToS.
