That's the cool thing about it, the delegation can be pulled in 1 minute and the 'monster' is no more.
I appreciate concerns, but trust these guys (whilst obviously working towards making a few STEEM for themselves) are trying to improve the place. Whether that be distribution of rewards, the trending page, or whatever. I say give it a chance, and if the monster appears, the bad press will spread like wildfire and the delegations will be gone.
Unless the ROI is super-profitable for them...sorry for adding this wedge here 😉
