If that is the case, then they should've blocked it many moons ago. Blocking it now is "theft" from them on a guy that bought what he believed to be valid SP. If they are NOW saying its no good, then every ONE of the witnesses that were aware the stake was ninjamined before this transaction should resign. If it is invalid now that Jason Sun bought it, then it was invalid before when Ned owned it. Where were they before? And why didn't they block it then?

This is not going to be good for Steem and will lead to lawsuits. Which they will lose on. And worse it will ruin confidence for a long time. There is no putting this genie back in the bottle.

And finally, stealing something from someone that bought something that was stolen is still "theft". Even more so when you consider the lords of steem allowed that theft to stand for many years without doing a damn thing about it.
