Coinhunter has admitted he can block transactions when necessary.
Proof? He sometimes posts "funny" things in IRC just to play strings on you here in the forum, in the case you didn't notice
Nobody needs proof that he can.
But in order to take SC seriously proof would be needed that he can _not_. Which could easily be given by releasing the source.
But this whole discussion is a waste of time. The untrue statements on silidcoin.info will trick people who don't take a closer look into investing funds, that's a pity but there is nothing one can do. Just like there will always be people stupid enough to buy CDSs from their banksters but neither is our business. People who do look and who do have a basic understanding about cryptocurrencies will not consider using SC anyways.
So why bother keeping this whole discussion up. Even the fact that from SC-side all this bullshit about 'collapse of Bitcoin blabla', 'Bitcoin is doomed and it's users will be 51ed in hell blabla' is being given out says enough about he spirit over there to just roll eyes and let those kids keep on playing with their big brother who tells them to build nice sand castles.
