I don't know about that but this often happens in the early days. The people running these tribes want to select a certain content. Often content that seems not fit for the tribe is downvoted and often they don't realize that by downvoting a post they also erase the hive value of it. For CTP Jon has created an account that has no hive power to do that but quite a lot of CTP tokens. Like that he can take away the CTP rewards but leaves the Hive rewards untouched.
