They can also learn by experimenting and watching other players. Which is what they do everytime they hit that multiplayer button and join a server. If anyone reeeaaaally wants to find a move you can google 'toribash moves' and I'm sure players know that, because the wushu sweep that has been around for ages is still being used. Plus with the tutorials and increase in toribash videos on youtube it is currently much easier to learn how to move for this generous of players by simply watching others (and the amount of tutorial videos as well). I'm not saying it's the worst thing in the world to copy moves, but I wouldn't recommend encouraging new players to only use those moves.
