I would create a brick-code, would insert it in any scene release that comes out, and upload these manipulated games/software to countless file hosters. I would spread terror and fear
There are so many ways you would get screwed by doing this, you would cause the company you work for a lawsuit, you would cause yourself a lawsuit, you wouldn't be able to sell your product in some countries because of this code (there are laws in countries outside of the US that prevent you from implementing things like this), not to mention its a complete and utter garbage move and would most likely ruin a company.
