I don't understand why anyone would want to do this? Unless Putin himself visited my site, then yeah middle-finger time but to paint the entire Russian population as hostile when the have about as much (or even less) say in what their leader(s) are doing as the rest of us do with our own bunch. I mean, Since when did a sternly worded letter to your congress-critter result in any policy change?
To each their own and if its your site then its your rules I guess.
