People here worry a lot about censoring content and preventing people from involuntarily seeing stuff, but I remember very clearly how irrationally triggered many maxis got that one time I said that I'd feel more comfortable using bitcoin as currency if the transaction required the receiver to accept it to go through.

I never got a straight answer about why that would be bad or not possible, just grunts.

My comment was based on my direct experience of someone getting arrested (and put in isolation and without any sort of rights or external communication to anyone, including their embassy, lawyers or family, for a couple of months), judged and deported for 10 years from Japan because someone else send them a tiny amount of hashish unbeknownst to the receiver.
