from average user point of view, it pretty much looks like this. The delegation rew. manipulation happened 1-2 months after start. You did NOTHING against that, so you were completely fine, most of people will lose very much on it - except the manipulator(s) and few other big delegator.
and top of this, it was running further, while they can sell their crap DVS, and of course, they undelegated couple of weeks after this wonderful event...
so yes, it pretty much looks like a SCAM!
and projects like this why I'm retiring from Hive...
