Funny timing.
I just had my GH account "flagged" (basically all interaction over web or API is locked, all open PRs wiped). No explanation.
Opening a support ticket is blocked by SMS verification. Which 429s. No idea if and how this will be sorted. Trust with some collaborators will definitely be hurt after the ban/flag even if lifted.
Really should have worked more on assigning another owner to the managed org...
So yeah, in case anyone who cares at GH sees this, account name profile.
