I'd never actually watched this before but the advice is perfectly reasonable. They're talking about if you're on the periphery of the impact zone to protect against flying debris such as glass mostly, and secondarily against some hot winds. Obviously there are many situations where you're fucked no matter what, but if you do survive you don't want a bunch of neck or torso lacerations from flying glass on top of everything else.
Their claimed territory spans 3 countries, which doesn't help their separatist movement. Those countries are now incentived to coordinate suppressing their separatism together.
Nations typically don't like separatist movements from themselves. Maybe there's more to it for why those countries don't like the Kurds, but that's probably plenty by itself.
Docker is fine for turnkey applications. Mounting external storage that persists across containers is a feature that enables that pattern.
Running Docker in a VM is also fine and has potential advantages. However I agree that it's probably overly complex for many people.
I'm confused what you're trying to accomplish here. Are you trying to make it look like the traffic is coming from your VPS for some reason? Nginx (amongst others) can reverse proxy tcp traffic.
Mostly gig job type things. If you're in a very low income country something like mturk might not be awful. Lots of demand for AI training data labeling these days - this is work like drawing a box around a dog in a picture so a model can be trained on what dogs are. The pay is very low though because anyone can do it so it attracts lots of people from poor countries.
If you're not in a low income country then you need to be highly skilled so you can get things like programming or art gigs - I've heard of people doing those but I don't know the websites offhand.
The other option is stuff like stock market trading or crypto (ie gambling).
But yes, I'd assume the things people promote are all scams.
It sounds like the bigger issue was that the game was bad.
