I just heard confirmed news update that Roger Ver was released on bail, this happened few days ago so it's possible that he accessed his own bitcointalk account.
Has he even been extradited to the US? There is nothing in the news about it!
And in cases that involve extradiction process, you can't get out on bail, Spain didn't arrest him for a crime committed in Spain so they can ask for one, they arrested him on a demand from the US, they can't release him no matter what guarantee he comes up with!
Anyhow he was stupid, even if we ignore the traveling to other countries, from the start when he renounced his citizenship he gained a St. Kitts and Nevis one, a tiny country that has all the agreement possible with the US, so how exactly did he think this will work out?
He fled to St. Kitts and Nevis the same year these guys signed the FACTA (Foreign Account Tax Compliance Act) with the US.
