on the coinmarket thread a bunch of people were reporting the same thing, some people got through the process and for some people the site went down before they could click the confirm link, basically just luck of the draw.
When i initially went to the site it said it was offline and was just a cloudflare snapshot, but i just tried logging in and it let me so lol I would just suggest attempting to login every once in a while.
I was in the middle of writing the guy a PM and thought before I sent it i should try to login, lol saved him a message.
