Considering the risk level of investing or trading BLY, the 'someones' buying shares are those in these categories:
1. Super / pension funds or any other fund that invests money on behalf of clients they don't particularly care about. i.e. the money is mums and dads money or Mr. Rich Whale's money who dumps money into a fund regularly just for the sake of it.
2. Hedge funds with obscene amounts of money. A few million on BLY is much like a punt on black and doesn't even make the lunch room chats. These guys have so much money they will almost throw it away. Much like high rollers who play poker with 10K blinds.
Don't associate buying with a positive outlook on the company!
