Do they have an API for refusing to accept ETH mined via proof of work? This is a start, but personally I'm still never going to accept BTC or ETH as payment; their history taints them forever. The real value burned in the mining of these currencies is lost forever, and the people who did the burning should absolutely not be rewarded.
