Also contacted support about it, but no response so far...
The thing is I need to apply for jobs now. So it won't help my case as an entry level applicant stating that I know some C, C++, Python and JavaScript w/o any proof.
I don't know, I can offer my employer to send my works as ZIP files, but this might be akin to shooting myself in the foot. Why? B/c I got the impression that you are expected to show your projects using GitHub. I wish the phrase "nobody cares about your sh*tty GitHub" would hold true, but I had employers looking over my past projects.
When you are dependent on a platform, and you get barred from that platform, you pretty much loose an opportunity to improve your life - like finding a job.
But these kinds of denials of services seem to happen to people in other instances too (Gmail/Google). At least I saw that somewhere on HN...
Anyway, what now?
