Unfortunately, given the huge efforts that state and privately sponsored hackers have made from Russia and China, it’s a bit disingenuous for people from those regions to throw their hands up and claim ‘foul’ when they face tighter security restrictions. Though you personally may not have been involved, sadly it’s not possible to blindly trust email addresses from the region.

Don’t blame those of us that are forced to be a lot more cautious about internet traffic from certain regions. Blame those who have forced us to be more cautious.
