That is morally grey at best, definitely not friendly to try to rope people into a project that you feel might be a scam.
I saw the facebook adverts and read up on Chronobank. It might well rise in value, but it is an idea that will never actually work, so long term it is pointless. It just depends if Polonie adds it or not, if it does then it will pump and the ICO investors (those who them quickly dump) will do well, otherwise I expect that no one will do very well out of it.
