Also, I'm generally bothered by comments like this one that stir up the general human tendency toward xenophobia. We should be fighting that tendency within ourselves, not fighting the out group. Whichever group of people we want to demonize, we should remember that they're people just like us. We shouldn't punish the majority of them for what a minority are doing to us.
Most countries cooperate internationally in getting bad actors from hackers over pirates to pedos booted off the Internet and into jail.
The exceptions are China and Russia who won't do anything against any bad actor and India which is a big base for phone scams (as is Turkey for the European Union, but even Erdogan's regime is cooperating with EU police in taking down scammers).
I agree, the line between demanding at least some sort of common decency standards and xenophobia is thin in these days, but we have to get everyone on board to protect everyone else from rampant abuse.
