Ignoring them completely is the best alternative.
I first thought it was better not to ignore CW Faketoshi, because if we pretend nothing is happening, then we send a message to agree with what he says and does. Then I decided that everything had already been said and there was no point in repeating what had been said so many times, until the lying bastard started attacking Bitcoin and the people who support it by using the courts in US&UK.
As a result of maintaining anonymity and ignoring the problem, Faketoshi succeeded in court that the whitepaper must be removed from
Bitcoin.org, and also received special recognition from the
Council of Bogota (Columbia) recognizing him as Satoshi Nakamoto.
People like CW should not be ignored, because they are not only people with dangerous intentions, but also people who have a lot of money with which to achieve their intentions. In the picture we see people who believe that Faketoshi is a real Satoshi, and if he can convince supposedly intelligent adults of a notorious lie, what can he do with those who have no idea about the basics?
