Looking for answers on a site that just furnishes answers you write down and turn in is "cheating." If you're a Democrat, I suppose that is OK, but for everyone else there should be obvious pride and ethical problems with cheating.
As for whether or not teachers know you're cheating; there is an Internet services used mostly by colleges (but catching on more and more in high schools) that permits teachers to go to a special site, enter a student's answers and then obtain a listing of every site on the Internet where that answer is posted. So a student who takes an answer at this site and submits it in an assignment using the same wording and syntax will eventually be caught.
