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.
If we refer to their emphasis on prohibited criteria - then all accounts sold, especially those that require KYC information, should also be prohibited. There's no confusion - this should be very clear, meaning if a newbie does it they will be banned, while users above them could be warned before bann or have their posts deleted.
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 accounts, accounts requiring KYC info, accounts created using stolen identities, accounts which cannot be legally traded, etc
So in conclusion - even if some other type of account is not on the list, but when it requires KYC information or something else then you should report it to the moderator to be handled. That much is clear - it is prohibited.
