Activate key/license XF Core/Addon validation against piracy

I have seen this XenForo was 15 years old and released from 2010. I think it’s time to make that XenForo core and addon that must have activate key/license to active and protect against piracy. This would save all developers to continue own addon. If they don’t and they would have lost money anyways no matter what that pirate will still continue to re-sell and because that they are rat. They made my heart broken of my addon have been stolen.

Stop piracy and pirate now!
