"Scirra.com as a service allows anyone to use the 'copy and paste' game code onto their own websites."
This is what I never liked about old Arcade and mostly the reason never published anything there besides couple of example files.
Basically anyone can "take" your game, put it on their websites and earn money from ads while people who made these game are unaware of the situation and simply being ripped off.
What is the status for new Arcade in that subject?
