Sanctions (outside of social ones) take time to investigate, so it does takes several weeks sometimes for things to cycle through their system. Sanctions very, very rarely are from recent actions.
That is highly likely. There was another case recently of someone in the same situation as you. Just because you didn’t buy illegal gold directly does not mean that you can’t get dinged due to being on the receiving end of dirty gold. It’s why there is always a warning to know who you’re doing business with. Whether you were blatantly aware of the gold’s origins or not, people can and have been sanctioned because of their place in a transaction.
Now, I will say that all of this is absolutely pure conjecture since I don’t know the ins and outs of what flagged your account or anything involving your case. What I just spoke on was from seeing another similar account closure case a few days back, and wanted to relay it along to perhaps offer some clarification.
