Question- Staining Tokens/ Blood Money

Are there any protocols (either in existence or planed) that allow Tokens to get "stained" if they fall in the hands of bad actors? Supposed for instance I am morally opposed to North Korea or other Autocratic Countries, and did not want to accept any token that has come from known accounts within those countries. Guessing they could be "cleaned" once they are paid as Gas. This kind of protocol could also be used to comply with sanctions I think… Guessing we need to have Identity built into the platform first…
