Well, the first filter catches anyone whose timezone is set to mainland China. That includes presumably all individual devs just using a VPN, who have no desire to or knowledge of distilling.

(Again, could be trivially bypassed either by rewriting, mocking the timezone call, or just changing the timezone. But we are assuming no mitigation used.)

Old Marv from Cocke County, Tennessee had a distilling lab too. I'm not sure if he'd have issues too. Well, probably many issues but unrelated.
