Services are added to this list when we come to believe that essentially no trades of such accounts are following our rules, which prohibit for example selling hacked
As you can see, there are just a few services that have been listed. It's as though trading other types of account (such as exchange accounts that require KYC) is still ok since they don't feature in the list, thus the confusion.
That banned services you quoted above was updated 16 May, which is pretty recent. Maybe after this your thread has served its purpose, the banned services thread would be updated again.
I believe any services requiring KYC allows only one account per user. So, CEXs fall under this category unless theymos says otherwise.
