the 50 miners on that pool could be the same person. At least it seems their funds get sent to the same poloniex funding account. They may have an arrangement to collectively sell the mining profits and send btc to the owners, that would make sense, easier if it's all automatic.
my guess is that it's a small number of people running the operation, perhaps only one. But they seem to know what they're doing and they are very welcome to help us making the burst chain much stronger. The stronger the chain, the higher the security and the more attrative the coin is, so it gets valued higher.
I think this is a good assessment. If you look at the timing of the Reward Assignments to the new pool they have obviously been done in sequence by the same person. So even if it is a "Group" then it is being managed by an individual. Amusingly the first payment to the new pool is from faucet.burstcoin.info
If you then delve a little deeper it becomes clear who is probably managing the "Group", however I will leave it to those that are interested to do their own sleuthing.
