How come you suspect they are? Let's take double-u as an example: he has been a part of the German community for many years, and hosted a place for chit-chatting on the chain every week (in German). When the blacklist was published he was very shocked to be on there. Since then, a few bigger German accounts delegated Hive to his accounts out of solidarity.
Would you really believe him to be a Sun puppet.
Also, there were very clearly defined rules. I believe that the blacklist should go by exactly these rules.
