No, the existence of clones is already a spoiler. So by saying your character is not a clone, you make it official that there are clones in Brawl.
EDIT: And besides, people can easily figure out that Falco is your character and if you say "My character is not a clone," you not only confirm the existence of clones but also the existence of Falco. HAHA.
Yeah true.. but it says *Spoiler* right in the title. And before you click it, its called *Character Spoiler*... so you cant even see the whole "My Character is not a Clone" part.
