I tried it multiple times in the past at different times and I was always shadow banned from the start. I think you could use it with Tor if you have it verified with a phone number or something else very personal, I don’t remember. But that defeats the whole purpose of using Tor Browser, so that’s not a possibility for me.
Also I’m not following the situation closely if it’s now different again or not, but which I doubt, because like I said, I tried it multiple times at different times in the past and was always shadow banned from the start. Even if it would somehow work today, Microslop probably did something good by accident and will find a reason to shadow ban Tor users again later. So Github for reporting bugs as a Tor user is dead for me. Browsing Github or downloading stuff from there is of course still possible with Tor.
