Well. If he is a hoax, why harass him, instead of not just letting him be alone? If it shows he was not a hoax, would it not have been wiser, to have ignored him, than to have harassed him? I dont really see the gain, in acting wiser, and claiming people to be a hoax? Hoax or not, either ignore or support seems to be the only wise choices?
Surely, they can get peoples hope up falsely, but - if you dont buy the things people say right away, however, instead observing if something actually comes from it, then I cannot really see the problem, or the need to spread negative criticism?
