Can't sign up to Dark Matter? : DarkNetMarkets | Torhoo darknet markets

With Archetype down I'm looking at new market places.

Dark Matter seems to be the most reliable (recent deposited issues aside) but when trying to sign up it won't let me. I'm typing in the usernames, passwords, pins etc. But when I click the 'Sign Up' button nothing happens. Anyone know why? Have they turned it off temporarily because of volumes?

Possible things I'm thinking:

I've disabled JavaScript via the security settings (set it to safest as on android about:config doesn't work). I've also enabled the NoScript extension but I do still get a pop up on this site saying JS is still enabled (not sure if it just doesn't recognise it has been turned off or if it actually is on) - Will Dark Matter not let me sign up if it thinks JS is enabled?

Or the usernames/passwords etc. are already in use or dont meet the minimum requirements. I've tried a few different usernames, tried more complicated passwords, tried 4 and 6 digit pins with no luck. It doesn't warn me that 'your username is already taken' or anything like that but wondering if that could be it.

Any ideas?

Thanks
