I don't really like this news. The good reputation of Bill Cosby is more than broken and i don't like it when his name is associated with Bitcoin. He is still a celebrity, but still with a bad reputation.
Bitcoin doesn't permit censorship of anyone. Even rapists. Rapists are allowed to hide their money just like all you tax cheaters. The blockchain doesn't care if you drug and rape women, if the signature is correct, the money is yours.
