Depends a lot on where you reside.
In where I live; no one cares for personal piracy. There have been local tracker owners busted; but the law enforcement did not go after each member individually; even though they could’ve according to law.
Legal ramifications? Highly unlikely; unless you’re explaining how to break copy prevention methods. That’s considered illegal in a lot of countries afaik.
As for lines you should not cross; I see ethics as more of a concern than anything. If you’re trying to learn how to use some software feel free to pirate it; but if you go into the level where you make a significant income out of it; you really should pay for it.
F to a rare theater quality rip releaser.
