All I see on those accounts is they were logged in today.
Some people change passwords regularly (I do sometimes - to many hacks around).

But to say the trough there are some major red flags here.

On the other hand, remember that hash? Huge buy walls? Current one at 50 (even after all the FUD and no login)? Virtually no sell orders?
He is definitely playing the crowd. Glad I did not touch this one, although if he is up to deliver - scooping up might have being not the worst way to go.

But if he truly works on the road-map (which I doubt btw) he should be smart enough to understand the more people are involved the better community is forming. Controlling huge percentage of coins and making superb product do not go hand in hand. Smart people will know what he did and will never buy it.

All in all. Do what you wish guys, I think this one might be kaput.
