I think we are witnessing two different series of events.
1. Bruno made a plead, just before he died.
2. His account was sold/hacked.
The way I see it, the hacker/buyer waited for the funds to be moved by Bruno's family, to start posting using Bruno's Cage account.
If that hypothesis is correct, then the imposter will never be able to sign anything from the plead donation address.
Or the person who made that donation thread was whoever Bruno sold or gave the account to. That would be the more likely situation in my opinion.
Well, that's your opinion, not mine.
I'm seeing two different personalities here, based on what I read and feel, exactly as I already mentioned.
What needs connecting, is the dots after Bruno's death.
I believe he was in control till then, and his death
synced in just fine.
So the main question remains, hacked or sold?
Hacked is the obvious reply, all things considered.
