He is a clown and nothing more. Keep it simple
For me its gonna be good if we can prove his claim is totally void and this will save Bitcoin's reputation for those who really doesnt know the truth.
Careful with this line of thinking. The onus is not on us or anybody else to prove his claim is void. The burden of proof is on him to substantiate his claims, and to date he has presented exactly zero solid evidence that he is Satoshi. He can't even sign a message, which is the lowest amount of evidence needed to even begin to discuss his claims.
If I claim right now that I am Satoshi, then I will have made just as compelling an argument with just as much evidence as CSW has. We don't have to prove his claim is void because it
is void until he proves otherwise.
If CSW wants to live in a fantasy world, let him. That's his right and it doesn't matter if part of that fantasy is that he created bitcoin.
It does matter, though, when he commits identity theft and co-opts Satoshi's name and reputation to run a scam. It's obviously bad for the newbies who don't know any better and get ripped off, but it's also bad for bitcoin. It sullies our reputation, it presents a bad image to the wider public, it turns off honest users, traders, merchants, and it hinders growth and adoption. If he wants to live in a fantasy world, then be my guest, but when his delusions spill over and start affecting others, he needs to be shut down at every opportunity.
The onus is definitely on him to prove his claims but he cannot provide even one iota of evidence. That has been the regular pattern on his part all along.
As long as he keep destroying the reputation that Bitcoin has and keeps claiming to be Satoshi he continues down the road of deception. Bitcoin does not need him but he living off the Satoshi and Bitcoin name.
