That's an interesting attack. If anything is given away, such as points, then it may be exploited. I do think there should be further requirements to get a delegation. It's pretty easy to build the reputation up a little.
If their plan had worked then they would get a nice chunk of HBD, but the proposal would need a lot more support. Even established projects can struggle to get the votes.
I could create a few hundred accounts for free if I wanted to thanks to my HP. Not that I would use them for evil.
We have to learn from these experiences. As Hive grows we will see more attacks.
Me too, but atleast some miniumum rep would eliminate thousands of new accounts created just for this purpose.
I remember even Ecency having tough time last year to get their proposal renewed. So you are right, it won't be possible this easily.
