Internet is global, there are no borders.
We could build an internet wall. I've contemplated whether it's a good idea or not. You see some guys make the claim that christianity is integral to western civiliation, right? And it looks like it might be wrong at face value, but if you watch one of these hidden camera TV shows where they have a 100% functional bathroom then randomly call in 30 plumbers to see who tries to rip them off, you instantly realize how this might all be related.
Out of the 30 or so plumbers, like 20 of them will be brown people, with a lot of those being Indians and Pakistanis. Literally EVERY SINGLE Indian or Pakistani tries to rip them off ALWAYS. The biggest concentrations of scammers in these things seems to be from non-christian nations (which are coincidentally mostly brown nations). So either a lack of christianity makes all these people psycho-scammers on steroids, or it's just brown countries in general.
The Indian guys also did weird shit on hidden camera like piss in a bucket on the floor then dump the bucket into the sink when there's a working toilet right in front of them, but that's a whole nother story.
