If people in both countries can access Reddit in addition to multiple other social media sites, then this idea of blocking a narrow set of .ru domains to obstruct spies cannot pass the sniff test. What an idiotic post. Being pro-Ukraine is one thing, assuming Slashdotters will fall for such moronic argument is quite another.
BTW, did the US block access to any official Iraqi websites in 2003? More recently, Iran has been implicated in assassination plots against Trump. Has the US government blocked any Iranian domains in accordance with your brilliant plan for obstructing spies? Of course, not, because it's like trying to dam up a river with your hand. "Just like everyone would"... pffft gtfo, go rile up some tech illiterate boomers on facebook or wherever you came from.
