The right to freely trade is a basic right, as is the right to refuse!!!
I'm not sure about the right to refuse. If you refuse to give service to someone, for example, because they're black, that's discrimination and a crime in certain jurisdictions (it should be everywhere).
Haha I don't think anybody is convinced with this app...
I still don't know what constitutes a 'dirty' coin... it's open to interpretation. DieJohnny wants to impose his morals on everybody.
And who proves these coins are 'dirty?' A 3rd party? And who's to say those coins aren't ALREADY in your possession and this 3rd party deems them 'dirty' later?
