Most platforms do not have a rule that directly says you cannot borrow the layout or structure of someone else's profile. What they care about is whether you copy the exact words, which can be flagged as plagiarism. Structure itself, like how someone arranges their bio or lists their skills, is not really protected. Still, writing your own profile from scratch is always better because it sounds more like you and clients can usually tell when something feels copied. Have you ever modeled your profile after someone else's?
