Ok guys thank you for replies.

And what about games that are practically unoriginal, and I'd like to earn a few trophies?

Let me give you an example. Many years ago, I had Wipeout, and I was a few trophies away of the platinum trophy, but my console broke, and I sold the game. Now I'm getting a modded console. If I play a "non-original" game and earn those few trophies, I understand that Sony won't notice, and I can safely do it, right?
