Complains that this hack is using the Soul Calibur II model, which really isn't a big deal, whether SSB4 Link looks like that or not (he's got the shading for the part, though), and the person who created/released that model as a hack was credited.
EDIT:
I made a mistake with another hack... I read the description, which told me that I'd be redirected to an Ad.fly link before I get to the download, and reported it. But when I clicked the hack download from the Vault, I was taken directly to the download rather than an Ad.fly link. Whoops.
