I
think CoinHoarder is a delgate.
from another forum:
Please vote for delegate.coinhoarder
Congrats, now hack my computer to find my delegate node and you are 1/51 of the way there.

Then you must do the same for 50 more delegates, and you code an attack script.
Then we notice your attack and vote the attacking delegates out of power, and roll back the block chain to just before the attack started.
Then life moves on and we laugh and tell stories about it for years to come.

This is exactly why PoS coins will never succeed. If you are able to roll back transactions of what you think are an attack on the network then you can roll back transactions on people who are simply unpopular to the network. This will make it so people will be afraid to use/adopt the coin because they will be afraid what they are doing is unpopular enough so any payment to them would simply be unwound.
