We should be alarmed as this is organised. Most of this accounts are free and fake accounts which are automatically created. How many accounts can one bot create in a day? Ten? Hundred ? Together with 15 SP for each account and some Steem for those shitty intro-posts which are funded too. So such a bot can make 150 SP or 1500 SP a day or even more together with 10 or 100 Steem and I have seen such bots accumulating and transferring power on steemd.com .
