Yes, they already paused new registrations just like other exchanges. I think that's a good move as of now for them to resolve the pending issues.
It's a good move in the way that other new users don't have to suffer from their incompetence, but this incompetence prevents new money from flowing into this market, which is what people don't seem to understand. Exchanges have had plenty enough time to hire more capable staff members, but the problem is that they don't won't to invest too much into expanding their service, which is a shame. Infrastructure upgrade is one thing, but hiring staff members is equally as important. If you want to be a major player in this market as service, then act as such.
