Does wordscapes dump cheaters?

This is like asking, does the taxman make all those who do not pay taxes, pay taxes?

Does a teacher, does a teacher make all of those who cheat on a test, retake the test?

There is never a way to catch all of those who cheat. You might even know one who cheats. The one who cheats is the one who has to live with it, where is the benefit for them? What goes around, comes around.
