Streaming
 

Is streaming shows or movies from a website or an app illegal? A friend of mine showed me the showbox app, it interests me. I was thinking about getting it on my pc, so I thought of asking, could I get in trouble?

Nah.
Streaming doesn't allow you to keep an accessible copy of the episode on your hard drive.

So, my internet provider won't stop providing? I heard you might get some warnings and if you keep it up, you're done.

You have to be a really active torrenter in order to get noticed.
Some Internet providers will give you a warning but never do much else.
There are very rare cases where someone downloaded one small thing and got sued up the butt for it, but you're unlikely to run into trouble.

Yes, streaming anything from a site or app that doesn't have permission to stream it is illegal.

Is it wrong that when someone quickly posted all of the Ninjago season 6 episodes on Youtube I downloaded them before they were taken down?

Legally? Yeah. Morally? Interpretations vary.

The Feds will track this within seconds and come to your house and break down your door and put you in cuffs. They might also eat some of your leftover lunch in your fridge while they're at it.
