...I left the people scammed. For my defence I sell those for fraction of the full price.

Wait... Your justification is "I only scammed them a little"? That's not really how that works.

In another comment you said you regretted doing this, but that's pretty hard to believe when you say something like this to try and defend yourself. It's bad enough that you're trying to defend yourself, but using "It was only a smaller amount of money" as the defense is even worse.

It's pretty clear that you either don't fully understand that what you were doing was wrong, or you don't really regret what you were doing.

I find online free keys for various antivirus products and sell those.

He charged money for something that was freely available. Just because they're real, and not fake doesn't mean it's justifiable. The refund part is completely irrelevant. The scam was complete before the key was blocked.

A good friend of mine is working on an induction furnace/forge. They are indeed cool, I fully support that project, if you decide to do it.

What are you going to build next?
