I didn't manually put 0 in front of my ID number.   And I always received "Sorry, but that Bitcointalk profile was already used'" answer after submitting, tried two or three times to make sure it works and that's it. There's just a few dozen participants in total, it would be stupid to try to fool the system since most of these signature campaigns are manually checked. And what kind of cheating is this anyway?! I submitted the same application with exactly same username and ITNS address - how would that even work since it's the same user that is applying? I really feel cheated right now, no idea why on earth you'd consider anything sneaky about this.
