What address is the private key to? Can you sign a message from it? I would think that would be harmless.
Are you sure GitHub did not auto "update" all profiles around the time it is showing as being last updated?
Obviously his private key is somewhere in the public domain. If you cannot post the address, was it the private key he held the forum bitcoin in?
I've asked to a friend of mine that is quite good with this kind of thing and he said is a manual update, someone should be doing it. I'm not sure of it since I do not know anything about GitHub.
For the address, I can sign a message but you will see the address, as I said I will share it only with theymos if he wants it.
No, it is a useless address with only a few transactions on it and it wasn't the address with 250 BTC.
I have a lot more to share about it but someone can think is inappropriate, so I don't know if I will share it publicly.
Ah, I was under the impression you would only share the private key with theymos.
Theymos (presumably) has paraipan's dox, as I assume it was given to him so theymos could file tax forms in relation to paraipan's payment he would receive for holding the forum's money. Unless you have information to suggest paraipan had multiple IRL identities, or that he faked his death, I am not sure how much value this would be.
theymos also does not appear to be especially interested in playing an active role in recovering the money, perhaps out of fear of violating debt collection (and similar) laws.
