GP is correct that OPs post makes no sense. Most validators around the world seem to be under no under legal obligation to exclude TC transactions from the blocks that they mine, and in particular to follow TC sanctions - their local laws don't require it, US law likely doesn't require it, and morally they are free to ignore US laws. Whether those in the US are/will be is clearly uncertain. If OFAC or the DoJ wanted to, they could state their opinion on the matter, and a court could decide if they are right. That this very normal process of a rule-of-law based society is not working in the US (the government embracing vagueness coupled with insane punishments) is an issue.
