Yes it does. EDIT: I just uploaded one with NO AUTH or Cost. But its not my full trainer. ALSO: It has come to my attention about the "posting username and password" part in the login freaks some of you out. But its just posting it to neopets.com xD
Debomb, since it's trainer, he can do whatever the hell he wants with it. And cheese, I've used it several times on my main and not been frozen. However, when I used it on a newbie account ti was frozen almost immediately, but that was probably because I used it for AA. Anyways, game trainers are always low to no freeze as long as you don't send your score too quickly and you don't send a ridiculously high score. To be safe, keep well under the review score when you can.
